Path problem on Windows 8.1

[handsomedave]

Blender 2.75a Try to render a simple scene and get the following in the console:

ERROR: ('Export path [E:\RenderManTest\Scene_0001.exr] does not exist.',) Error: PRMan: Exited

It looks to me like whatever is building the paths is adding extra backslashes.

[bsavery]

Can you give me some more info? What are you setting the output directory to? E:\RenderManTest\?

[handsomedave]

In Renderman Output property dialog RIB Output: E:\RenderManTest{scene}.rib Display Image: E:\RenderManTest{scene}_####.{file_type}

In settings under Add-ons OUT(Output Root) E:\RenderManTest\

RIB is created when I try to render. In the error message all backslashes are double ex. E:\RenderManTest\Scen.......

If I change output property dialog settings to: RIB Output: $OUT{scene}.rib Display Image: $OUT{scene}_####.{file_type}

I still get the same error.

[bsavery]

Sorry Are you on windows, linux etc? I'm guessing Windows from the above but what version? I ask because other's on windows don't seem to have that problem. Maybe a permissions issue?

[handsomedave]

Sorry put Windows 8.1 in the title, should have also included in post. Tried running blender as administrator and it made no difference. I don't have anything running other than basic antivirus and have tried disabling it. Which python file does file writing take place? My pythons far from great but I could try and hunt it down myself.

The RIB file is written successfully in the same folder that image output should be written to.

[bsavery]

Oh ok. Hmmm. So you get a E:\RendermanTest\whatever.rib file? What is in the rib file if you open it in a text editor for the "Display" line? Maybe if you can attach your scene somehow that might help.

[handsomedave]

Below is the contents of the RIB file. I noticed that if I create Test.exr before rendering that the file is deleted when it fails. My scene file is just the default cube with PRMan selected for renderer and the file locations for the RIB and EXR changed.

Figured out what the issue was. If RenderMan is installed to a non-default location PRMan-for-Blender does not work correctly.

Reinstalled RenderMan to default location and corrected issue.

[bsavery]

Interesting. I think that should work, you just have to set up the environment variables manually.

[JiayinCao]

I am encountering the same issue even if renderman is installed at default location which is: C:\Program Files\Pixar\RenderManProServer-20.1\

[MWY3510]

JerryCao1985,

Can you show me what your RMANTREE environment variable looks like?

[JiayinCao]

Sorry for the delay. Following is my detailed setup in blender:

RMANTREE Path: C:\Program Files\Pixar\RenderManProServer-20.1\ Render Path: prman ShaderCompiler Path: shader Shader Info Path: sloinfo Texture Optimiser Path: txmake OUT(Output Root): D:\prman_for_blender{blende} # I changed it to drive d so that I can avoid permission issue SHD (Shadow Maps): $OUT/shadowmaps PTC (Point Clouds): $OUT/pointclouds ARC (Archives): $OUT/archives

I've also tried the 'Use PRMan default paths', no luck on this option too.

I would be really appreciated for any tip that helps.

[bsavery]

So the problem here I think is that your rendering on a different drive than where the add on and prman are. When creating the rib file we try to construct the relative path from where you are rendering to the add on and Prman. And windows of course because drive letters doesn't know how to do this.

As a work around I bet if you doing everything in c: it would work fine.

I'm afraid that it doesn't... Actually I tried to export those intermediate files to drive C first, I changed it to drive D in case there is a permission issue. However I do can see some files generated, such as c:\prman_for_blender\untitled\Scene.rib and folders called 'archives', 'images', 'textures'.

Here is the error log output by PRMan:

ERROR: ('Export path [c:\prman_for_blender\untitled/images/Scene_0000.exr] does not exist.',) Info: Texture generation took 00:00:00 Info: RIB generation took 00:00:00 Error: PRMan: Exited

And the Scene_0000.exr image is not there as it complains.

[bsavery]

Ok I'm not sure why the revers slashes don't work for you because they seem ok for everyone else on Windows. Should be an easy fix though

Brian,

Are you already working on this issue, or would you like me to put it on my list for tonight?

[MWY3510]

I think I have most of the reverse slash issues tracked down.
