Rendering issue

[Anonymous]

For some reason when I render, the wood texture that I manipulated in the UV does not appear to be working once I render it out.  Any thoughts? Using Maya Hardware 2.0, Maya Hardware cause more problems when I try it.

Hi @Anonymous

Thanks for posting! Would you be able to post your scene so I can have a look at it on my machine? 🙂 You can either send it to me in a private message, post it on here (.zip file), or upload it to a drive like dropbox and send me the link to download it.

If you cannot share it, can you tell me a bit more about the shader itself? How did you create it? I can do my best to replicate it on my side.

Thanks for your time! I look forward to getting this resolved  for you 🙂

Here is the zip file.  In the UV editor, I select the mask (both sides) because for some reason its not one UV layer.  I rotate it and translate a little bit to create the vertical pattern.  In the test render view, it works.  Once I render out a frame it reverts back to the original pattern.

Hi!

You can't manipulate  3D procedural textures like "Wood" by using UVs, they are independent of UVs.

The changing preview by editing UVs in Viewport is a bug of Maya-Viewport.

Simple change a value for any Attribute of "Twig_Rig_35:Wood" to force a Viewport refresh/update.

Hi @Anonymous

Thanks for your patience with this one! I wasn't able to get the same results as you. I rotated the UV's around just a bit (not as much finessing as yours, I assume) but the preview render did match the output render for me. Here's my saved JPEG:

Can you clarify what your process is for manipulating the UV's? What tools are you using to do the test render versus the final render? Happy to keep testing until we figure this out!

Thanks for your patience with this!

Hi!

@Anonymous and @jordan.giboney.

To be able to display 3D Textures, Maya needs to bake the texture, as background process, on the object as 2D texture (only for preview in Viewport).

Editing the UVs and by this changing the look of the 3D texture is only possible due to a bug (cause you only change the temporarily result baked for Viewport).

Please read my message above for further details.

If you want to use UVs you need to convert/bake the texture to 2D or create a new 2D texture.
