Thank you for the information. Would you mind to create just a very small example of the issue which comes up in the Share? I have tested and for me, the number of channels in the GDTF Share is always correct, see the test fixture here. Feel free to edit it to demonstrate the problem. The 3D representation is not important, only the geometry linking and DMX. Thank you cc @vvasicek

Hi @Petr Vanek - Robe, There are two different issues. The first is that if a reference geometry with an override break set is duplicated, the override value is not retained in the duplicated geometry; it must be entered manually. I'm currently using a tool other than the builder to resolve this issue, as manual entry is not an option. The second issue is that the total channel count displayed for modes on the share page is incorrect, because the count also takes into account the channels of the override breaks and therefore adds them. This is a display issue only on the share page; in reality, the total count is read correctly from the console. The fixture I'm talking about is in wip, if you want you can share a contact with me I can send it to you privately because I can't make it public yet. Thanks. Best regards.

Hi @Prolights, I think we are maybe talking about different things? As long as the DMX breaks are set correctly, the GDTF Share should display it OK. But if at the moment the Builder does not help you to quickly set the offsets, you need to adjust them manually, for the GDTF file to be correct. Can you please clarify which if these issues are you having? Thank you

Hi @Petr Vanek - Robe, Is there anything new about this? Unfortunately, this issue is causing quite a bit of confusion when displaying DMX modes in the share because, as shown in the screenshot, the total count displayed is false and can be misleading. Thanks. Best Regards.

Hi There, something strange broke here. With "Use Parent Physical", the values on the channel set do not match those in the channel function range. Any suggestions? Thanks. Best Regards.

It is important to mention the exact GDTF file. In case of a vendor specific issue (like this one) best is to go directly to the vendor - Vectorworks forum. I looked at this official file briefly in the GDTF Builder and in BlenderDMX and it seemed OK, but details might be important so please check directly with VW support.

Issue confirmed, reported to developers, thank you for the report.

HI @Prolights, we need to re-check because i think this was already working correctly.

Hi Everyone, An update and more info on the issue. For now, the best solution was to edit the file in grandMA3 and get started right away. Another note regarding gdtf-share is that once you reload a file with 441 channels on Break1, 441 channels on Break2, and 441 channels on Break3 using Break Overwrite, the total channel count displayed by the share is 2934 channels instead of 1323 because it counts like this: Break1: 1 to 735 (RGB Instances from 1 to 147): Break2: 440 to 1026 (RGB Instances from 148 to 294): Break3: 587 to 1173 (RGB Instances from 295 to 441): In practice, the channels of the overwritten Breaks are also counted. It's just a display problem in the share because in reality there's no problem with the patch. Thanks. Best Regards.

Hi everyone basically, when I try to duplicate and arrange a geometry reference that has Break 2 and a DMX channel set to Overwrite Break, the break value is not retained in the generated copies. I expect that if I have Break 2 on the original geometry reference, this value will also be retained in the duplications. However, once the duplication is completed, the Break field in geometry remains blank and must be filled in manually, which can be extremely slow on dozens of pixels. Thank you all. Best Regards.

I’m having trouble with something that seems like it should be a simple fix; I’m working on getting the profile for the Chauvet Strike Array 4C’s to render its beams correctly. It’s a 4 cell RGB LED crowd blinder. I can’t seem to find the right boxes to tick to link the individual cells to the main beam control. Currently the beam looks like it originates in the center of the fixture pointed downwards… in the geometry editor it looks like everything is placed correctly but I can’t figure out what parameters to link to get it to look right. I’m pretty new to working on GDTFs so any help would be appreciated! I’m using Vectorworks Showcase to visualize if that helps. Thanks! Attached is a view from the back in Vectorworks with the GDTF that Chauvet made so you can see what I mean.

Hi chat, I have published a GDTF Editor VSCode extension, https://marketplace.visualstudio.com/items?itemName=dmxout-hippyau.vscode-gdtf It does not do everything, but if you have xmllint installed, it will validate the xml against the GDTF 1.2 schema, and show problems. It provides an "Outline" section too, and shows wheel images, and colour swatches. Issues and PR's are welcome... https://github.com/hippyau/vscode-gdtf-editor Cheers, Hippy

Hello everyone, grandma3 doesn't want to set by default the open channelfunction. in grandma3, clear clear goes to dmx 0 in gma3 editor, everythings are good. default channel shutter to open 254 do you have an idea why there is e bug? thank you SHEHDS@230W_7R_Beam_Moving_Head@mars_26_V25.gdtf

Thank you

Hello, controlling rings of LEDs can be seen in several fixtures in the GDTF Share, you can look at the Robe Arianne 6, or the the Robe LEDWash 600 to see how it can be done.

Hi, its my first time creating a file for a fixture and I am struggling to get everything working as it should. I have a Beamz FUZE 1910 and you should be able to control the pixels in 3 sets (the centre, middle ring and outer ring) does anyone have any advice on how to get this working. Many thanks, Liam

T918 is in GDTF showfile. I build it. Not yet perfect but good workable making updates often. Strugling with the led ring to get it to work in the visualizer.

masterpiece! thanks

Good day. I'm new to building GDTF files. And I'm just struggling with it. If there is anyone that can help me by building it. It would be much appreciated. The fixtures Are the following. V-SHOW. S710 profile BL200studio Blinder T918 R740L

What you want to look at are DMX breaks on Geometry References, you can define them either in Channel Function directly, or on the Geometry Reference, if you enable the Break Overwrite. The Break will create a new "DMX patch address" in gMA3. See more below. The fact that you can create this on the Geometry (Break Overwrite) allows you to do other things too, for example we define a single geometry tree for the Spiider and in some DMX modes, by using the Break Overwrite, we can define different offset (for RGB vs RGBW channels): cheers Petr

Hey. Thanks for the reply. I know how the reference works, and it's not what I'm looking for. For example, we have the aforementioned 21x21 RGB pixel matrix. The idea is to create a mode that can route the signal to a group of pixels to reduce the number of necessary parameters without having to change mode on device. In a 21x21 RGB system, there are 1323 channels, but if we create a matrix of 9 pixel groups, we create a 7x7 matrix, which takes up 147 channels. The idea is similar to multipatching in MA, to send a single RGB signal to physical pixels 1-9. The idea is to create a multipatch, but from the library level. I expect this isn't feasible, but it's worth asking. Perhaps this is also a note to MA and to you about implementing a new feature, in an era where the number of parameters is multiplying like Easter bunnies 😉 cheers

Hello, yes, you can use Geometry References in GDTF, this allows you to define an element once and use it many times via the geometry tree, it is then used by grandMA3.

When writing a library for a multi-pixel device, e.g., a 21x21 RGB matrix, the device takes up over 1,300 channels. Is there any way to create something similar to a multipatch from the GrandMA system, but at the GDTF level, so that it would later be readable by GrandMA?

How to implement rgb led ring on front of a beam fixture? I cannot get this to work. If I have the beam working then the ring doesn't work and I have the ring working the beam isn't working. In geomtries I have Beam and ring under each orther. Beam is set to geometric type beam when I set ring also to geometric type beam the ring is working but the beam not anymore. If I set the ring to colorfilter the beam is working but the ring not. Which geometric type the ring needs to be? The ring geometrie is behind the Beam geometrie. Ring geometrie is 20mm wider than the beam geometrie so a ring should be visible. Do i need to override something under DMX with "add relation"? Tried erverything but can't get it to work in GMA3. Anybody know any working example fixtures?

Hello Mr. Vanek, I have dealt with 2 out of 3 problems that you can have presented... I have decided to leave the fixture facing up instead of down, because when i do I get an error message about it not being at it's origin point. Anyways, if you could sir, could you please take another look at what I've got now? I am on Revision23, and my problem is that in MA3D Beams will only show when: - Dimmer is On - White is On - Strobe Is On Also, My RGB channels do not work at all in 3D. Thank you sir. https://gdtf-share.com/share.php?page=home&manu=Rockville&fix=MOTIONSTRIP&rev=131546 https://fixturebuilder.gdtf-share.com/fixture
