i create volumetric object and i add material with gradient opacity and uv channel
when i save the scene and open it the parameters of uv channel reseted
----
i use two gradient procedural texture for the opacity of volumetric ; i disable one and enable the second; the result is black render and when i removed the disabled procedural the render was clean

[seghier]

if we apply material with opacity texture without set uv channel to the volumetric, the studio force closed

Hello Seghier,

can you post a scene to test ?

Thanks.

Hello Miguel ; this is the scene
https://www.dropbox.com/sm/create/Public/volumetric.rar
; when you open it changed the parameters of uv set ( rotation x;y and scale x )


when i clone the volumetric the new one don't have uv set

Hi Seghier,
when i try to open the dropbox link it says

Error (404)

I created a dropbox account just in case but to no avail.

EDIT

There was a bug in the procedurals that, when you had a material with a texture and the procedural object (volumetric, particles, etc....) didn't have a uv channel, studio or maxwell crashed when rendering. It has been fixed just this morning. It will be published in the next update.

oh sorry i check the link and the file removed ! i don't know why
if you have email i will send to you its very small scene
thanks for fixing the bug . and parameters of uv set of volumetric reseted when we close the studio and we clone it . the clone does't have uv channel
can you make volumetric have uv channel by default like other objects

this is new link

i convert the procedural gradient to image and tried again but studio crashed
other question
i use volumetric inside volumetric ; and apply rough glass to them( i will post render soon)
i see in the render like thin horizontal and vertical lines ( color effect )

[Miguel]

Got the file, thanks!

I'm investigating why the parameters of the uv channel change after loading, and why cloning the procedural doesn't preserve uv channels.

Thanks a lot for the report.

In general, if there is a material with a texture (either image or procedural texture) applied to a procedural geometry (particles, volumetric,...), this resulted in a crash while rendering. This has been fixed now.

Cheerios.

many thanks Miguel
you can try this scene ; i use two volumetric and get like lines in the final render

when i move the pivot of volumetric ; in the viewport only the pivot moved but when render the volumetric moved
