Light beams of GDFT Fixtures in Vision 2020

Recommended Posts

Posted (edited)

Hi, I have a problem to visualizing the light beams of GDFT Fixtures modes in Vision 2020. When I import an MVR file created from Vectorworks, the light beam of the GDTF fixtures is displayed or not depending of the pan and tilt position of the fixture. Then, I have uploaded two images and a video to explain the problem. In this example, I have mounted 5 Martin MAC 300 in 4 Vision mode and 2 Robe Robin LEDBeam 150 RGBW in reduced GDTF mode that I downloaded from gdtf-share.com.

 

When I connect a lighting console ETC EOS using Artnet and turn on the fixtures in the Home position, the light beams are not displayed on the fixtures in GDTF mode.

If I modify the pan and tilt position of the fixtures, the light beam is shown on some points.

In the following video, It’s clearly seen how the light beams of the fixtures in GDTF mode appear and disappear while the tilt parameter is moved all the way. I have also turned on the MACs 300 in red to see if this also happens in the Vision library fixtures, but in this case it works correctly.

 

This happens on any type of GDTF fixture that I import into Vision. What could be the problem? Is it a GDTF file problem or a Vision problem?

 

Help me! Thank you very much.

The only problems I have had using GDTF fixtures in Vision (for demo's and at trade shows) has been due to content errors in the GDTF's themselves!

That being said I haven't tried to use both GDTF's and the older Vision lit fixtures together in the same file. As far as i am aware as long as the GDTF itself has no bugs in it you should be able to use both formats in the same file.

Could you post the file you are having problems with so that I can test it?

Also to confirm, which GDTF fixtures have you had problems with when merging into your file in Vision?

 

Image 2 however is not a bug,  check your haze settings. It looks like you have the 4D haze texture selected. This is designed to more accurately visualize the way haze and smoke works in real life, where you almost never have a perfectly uniform haze density. This is why  beam is not visible for its whole length.

if you adjust the haze intensity, the haze texture intensity and or the haze turbulence you will see a different effect. or you can select a different haze texture

In the first place, thanks for the quick reply, Jesse.

I know. I have simply uploaded the images to compare how the beams are shown in the second and not in the first. The Pan and Tilt position of the fixtures is different in each image.

I have uploaded the MVR file in which I have experienced the problem, the GDFT file of the fixture I have used and the Vectorworks file from which I have created it.

I hope you can discover the problem! Thank you!

Hello everybody! I've the same problem: fixture in a place and beam in another...

Exported mvr from vw with gdtf mode. If I sent to vision all works well but I don't have the correct mode to set, this is why I choose mvr.
