Hi AyrtonTerrier, Thanks for reporting this issue. We can reproduce it and I will create a ticket. Best Regards, Daniel

Hello everyone, I probably found a problem loading the builder when you open the file from the GDTF share, It seems that the builder loads the file only on the fixture sheet. If you select another sheet before the file is completely loaded, it will not completely load the file and an error may appear. I have attached a video showing the problem The file used is the Zonda 9 FX from AYRTON 2024-04-24 09-30-22.mkv

GDTF Builder has been updated with the following changes: Ensure that when saving a GDTF file, the spinning animation is closed down after file upload procedure Improved GDTF Share performance when saving GDTF files Do not mark DMX Breaks with offsets larger then 512 as errors Ensure correct reading/writing of GDTF files after copy/paste of geometry references

Hello @Brothers, we are hoping for a fix for this to be released this week. It is pretty difficult to reproduce so we hope we are eliminating the issue. cheers Petr

Hi. I'm having some errors when I save a new fixture. I save the file like in the 1st picture: When I'm opening it again it gives me the following error: And when I check the same channel it looks like this: It happens for all "StrobeModeStrobe" and also for "Tint". After I do it again and save it a 2nd time it works fine. It happened for 9 fixtures since yesterday.

Hello Brothers, Thanks for the report. The connection of the grandMA3 to the GDTF Share is now working again. Best regards, Daniel GDTF Team

Hi, Is there a problem with the servers? I'm asking because until last week everything could have been found directly in MA3. Now every new upload(from the past week and a half) can't be found. I need to manually download them and import in MA3. It's not a problem, but it was easier to search the fixture directly in MA3.

If you have the opportunity, please visit the GDTF Booth in Hall 12.1 stand B41 at the Prolight + Sound. Open manufacturer meeting is taking place in-person at the GDTF booth, on Wednesday at 4:00pm. Location of the GDTF booth on the PL&S floor plan.

Hello @mgeasey@clearallvisualsllc.com, I don´t really understand what you´re doing to solve this problem. I converted a file for Martin MAC Aura XIP to grandma2 but 3d doesn´t work well (screenshot). Could you explain what you´re exactly adjusting

Hello @vixzy i looked at your file. The important thing to realize is that shutter is a different physical behavior then strobe. Shutter can be open/closed (1/0), while strobe is strobing fast/slow (1/s), so for example 20 for fast, 0.3 for slow. For this, define two channel functions, one for Shutter (Shutter1) one for Strobe (Shutter1Strobe): And then adjust the Channel sets to match the speed of the strobing. See attached file where i split the shutter into two functions. Kind regards Petr Etan@Etan_101@Splitting_Shutter_into_Shutter_and_Strobe.gdtf

Hi! Fooling around a bit with the profile i got it working in MA3 3D by changing the first logical channels "Physical From/To" to 1 in both fields. But is this the right way of building the channel? Etan@Etan_101@Rev_1.6.gdtf

Hello, Presumably you are adding Shutter instead of a Strobe, that's maybe why it's not working. Posting a GDTF file here can increase a chance that someone will look at it and can help you. Cheers P.

Hi! When I add any kind of strobe/shutter function to my channel i get no output in MA3 3D unless i bring the channel up to at least 45%. Judging by the channel list for the fixture i should have output when that channel is at 0 and different strobe modes after that. How should I define the Strobe channel for it to work properly? For the moment I cant get my hands on the fixture to see how it actually acts in real life. Its a led mover that one of our suppliers bought a bunch of a few years ago that we use from time to time All tips are very appreciated. Thanks in advance!

Hello @SergeG, is there a GDTF file you could post here for people to look at? cheers P.

Hello all, we have made a public release of the libMVRgdtf library which makes it much more easy for software authors and companies to be able to implement and utilize GDTF and MVR in their products. We had previously been giving access to the Github libMVRgdtf repo on individual bases, the code has now has been released to the general public. The implementation also included the MVR-xchange communication protocol. The library has been used ever since by the Builder and other software. License allows commercial and closed software usage, but IANAL, so check yourself.

I am trying to modify the latest library of the Chauvet f415 projector since the predefined color wheels do not work in the 3D view of the grandma3. I cannot separate the 2 wheels: I have to open the 2 wheels for the projector to start emitting a color, but the 2 color wheels are independent (a predefined color wheel and a temperature wheel color). How should I make this work?

GDTF Builder has been updated with the following changes: Undo for the Physical Description tab has been implemented. Ensure that CIE Color Space representation remains visible when picking a color Provide the GDTF file for download before uploading it to the GDTF Share Improve DMX tab editing performance

Hi Petr Thank you very much for your fast Reply and Help. Now it works as expected. Greetings Lukas

Hello Giannis, we describe the "quality" or "size" of the 3D asset by using vertex count, this being in the Spec and also in the Builder. It is a value commonly seen in 3D software like Blender. I am not sure what a "polygon" would be meaning here - would that be a triangle? As for the level of detail: One can use the provided GDTF Primitives of base, yoke, head, triangle, sphere... these have been created to be as simple as possible, when no other 3D asses is available. The "default" level has been chosen to be 1200 vertices for the complete fixture. A complete fixture "typically" being a moving head and this has been providing good guidance in our experience, as it makes people aware of the properties of 3D models. So for base/yoke/head fixture, this ends up being some 400 vertices per model. If the fixture has many lenses, these would typically be referenced, but when preparing our 3D assets, if we have a way to test in real software, we look at what the fixture looks like and ensure good first hand experience. The low level of detail allows to provide even simpler models with more decimation, i am not sure if any software is using this at the moment. The high level of detail is there to allow unlimited details to be expressed. Kind regards Petr

Hello, you cannot link the Wheel from the "fast shortcut" of the Channel Function, but you can add it if you open the full modal dialog editing the channel function properties: This then allows you to select gobos for each channel set: Depending on the use case, you will have to test if the software of your choice visualizes ColorMacro... Hope this helps Cheers Petr

Hi I am trying to set up the Eurolite "LED Strobe SMD Pro 132 DMX RGB" fixture in 4 channel mode. The channel 3 has diffrent colour presets. I have created a wheel and made a slot for each channel colour preset. The "ColorMacro(n)" attribute describes that the individual colors can be selected for the channel sets when the corresponding wheel slot is selected. However, I only have the option of defining Physical From and To for the channel sets which is only a numeric value. I cannot find an option to select a wheel here. At the "Color(n)" attribute, I can select the wheel as usual. However, I don't want this channel to react like a colour wheel in the visualisation, but I would like to be able to select the predefined colors using channel sets. How can a wheel be selected for the "ColourMacro(n)" attribute? Thank you in advance for your help. Best Regards Lukas

Could you please provide some guidance on what's the best way to ask manufacturers for the ideal 3D Files to provide all 3 LOD models for a fixture? I would like to have an easy explanation to a CAD engineer so that he can immediately translate the LOD in the table below: The model currently does not have any children. All models of a device combined should not exceed a maximum vertices count of 1200 for the default mesh level of detail. There are three level of details that you can define: Table 33. Mesh level of detail LOD Description Folder 3DS / gltf Low Optional; This is the mesh for fixtures that are far away from the camera. It should have 30% of the the vertexes from the default mesh vertex count. 3ds_low / gltf_low Default This is the default mesh that is used for real time visualization in preprogramming tool. It should have the minimum vertex count possible, while still looking like the fixture in 3D. 3ds / gltf High Optional; This is high quality mesh targeting non-realtime applications, where the vertex count is not that important. There is no limit for the vertex count. 3ds_high / gltf_high Low and High meshes definitions are optional. Place the file with the same name in the defined folder. Sending this table was not always accepted without further questions. For example, the polygon count is also asked back.

Ok. Thank you,

No, if the settings doesn't depend on some DMX value.

I'm testing a build fixture Brother_Brother_and_Sons@Compact_Fresnel_Light_-_Wide_-_Single_Color_5600K@REV0.gdtf in MA3. The fixture is Single Color, but on the Color tab the values for R, G and B show up(they don't work). How can I make them disappear, or I did something wrong when I created the fixture?
