Procedural Textures to Maya Nov. 30, 2020, 6:08 a.m.

Hello,
I noticed that in maya, the hda write a file. And he refreshes her every frame.

I am in the same case, I must read a procedural texture animated from an HDA.
But here the texture is baked in a png file and after read. This image is updated every time.

I'm looking for a more optimized solution without having to write a file.
Inside maya ,I don't know if it's possible to directly read the procedural texture with an output of the hda.

cheers

Problems about openCl. April 14, 2019, 1:24 p.m.

Hello, I have got Nvidia GeForce RTX 2070, and I use houdini 16.0 within my company.
I think houdini doesn’t use 100 pourcent performance of my graphic card for simulation.
For exemple when I make simulation whith openCl my GPU wasn't utilsed, and my log give me an OpenCL Exception: P (-33).

Is there any incompatibility with my graphic card or something has to be added or modified within the environment?

My complete log as follows

Thanks for your help

problem for render a Maya scene with HDA on a renderfarm Nov. 16, 2017, 6:08 a.m.

Hello,

I've got a problem when i try to render a Maya scene with HDA on a renderfarm. It shows me this error :
The attribute 'hda_test1.outputObjects.outputGeos.outputParts.outputPartMesh' cannot be connected to ‘hda_test1_0Shape.inMesh’.
This connection exists in the node editor and when I break it, the render works but I lost the HDA animation (just a deformation on a sphere by an animated noise).

Somebody have an idea ? I can't see my HDA in the rendered file.

I use Renderman 19 (Reyes) and Maya 2015. I have exported this HDA with Houdini 15.0.244.16.

Thank you in advance for your answers.
