The plugin does not work in blender 3.3 or 34.

Here is the error message:

crashes when trying to render specifically the 87th and the 92nd frames. choosing to skip that frame then everything renders just fine.

tested on blender 2.92 with the following file:
multi-view-cube-renderman.zip

crash log taken from the LocalQueue:

In the vein of making the controls easy for beginner users and then allowing them to go more advanced, I’m proposing making the sampling panel even more simple in «Easy mode».

Here’s how we could do it:

The render type would change integrators and settings like caustics, etc. Quality/Time slider would drive the max samples and pixel variance.

Vray does something similar:

Here’s a pretty annoying issue and one that might be worth fixing rather soon as it has an impact on many occasions.

When you use a render border in Blender to only render a part of the scene, IPR stops when you adjust a value in the Node Editor. It only seems to happen if the render region is rather small though. With bigger regions the connection to IPR stays intact.

I know this issue has been discussed before, but I couldn’t find any working solution.

It seems the addon adds superfluous slashes to my addon defined paths.

The addon works as long as I don’t use any renderman shaders. Then I get RenderMan: Exited

My defined path is (default):
C:/tmp/renderman_for_blender/{blend}

Addon makes out of it (error message system console):

How can I get rid of all those wrong slashes and backslashes? The dots should also be problematic on windows, but removing them didnt help. Also other HDDs and paths didnt work. (Windows 10, Blender 2.78c). Renderman is installed at default path and also the .license file…

Hello.

There’s an issue with the PxrRamp node when you create a Single-User-Copy of a material. If you do so, and change the ramp colors of the new material, the PxrRamp node of the material that it was created from, changes as well. This only affects the ramp slider and none of the value fields.

Here’s an example scene … http://www.andreasresch.at/upload/Renderman_Test_113.zip

Hello.

The size of a Gobo or Cookie seems to be different in the viewport and the actual rendering. For example — if a Gobo has a size of 4×4 in the viewport, it renders at a size of 16×16. So the render size is multiplied by itself.

Here’s a demo scene … http://www.andreasresch.at/upload/Renderman_Test_114.zip

Mixer when it can support renderman21.5 version because I am using maya’s renderman version is 21.5，I want to spare time to play a blender’s renderman

Environment:
Blender version: 2.78c
RenderMan version: 21.5 NCR (only one available for download)
RenderMan for Blender version: 21.4 (latest available)
OS: Windows 10 build 1703, 64-bit
Both Blender and RenderMan installed on D: drive.
Logged in as non-privileged user.

Reproduction steps:

1. Install Blender in non-default path.
2. Install RenderMan in non-default path.
3. Install plugin (Blender, File -> User Preferences… -> Add-ons -> Install from File…).
4. Try to click on empty box near «RenderMan For Blender» (with «Enable an add-on» hint).

Current result:
Stack trace from addon_utils.py, line 349 in enable mod.register(), as on attached screenshot:

Expected result (in order of preference):

1. Add-on successfully enabled.
2. Hint what should be done to make it work.
3. Explanation why it can’t work (for example incompatible versions of RenderMan and the add-on).

When i tried to render something i get error PRMan:Exited.
Console:ERROR: (‘Export path [C:/tmp/renderman_for_blender/untitled/images/Scene.0001.exr] does not exist.’,)

Blender and renderman installed in the default folders, licence is in the right folder.
I spent more than two hours trying to fix this problem.

I’ve run into a problem using materials which are linked to the object.
Ordinarily, setting a material slot to «Object» lets me change a material on one object only, even if it’s using a shared mesh.
Unfortunately, it doesn’t seem to work when I’m using RenderMan—it just uses the material which is attached to the mesh data, completely ignoring the one attached to the object.

This seems like it could be seriously inconvenient to not have. I’ve already run into some problems, and I hope you fix it soon.

Thanks!

Hi,

there’s a bug with the spot light. Both the Blender settings and the Renderman settings for the cone shape and softness affect the light.

When I start IPR, the Blender cone settings are used for the light. As soon as I change the cone settings in the Renderman tab, the those settings are used and immediately updated in IPR. Whenever I stop and start IPR, the preview always will start with the Blender cone settings.
For the final rendering, Renderman always uses the Blender settings and ignores the Renderman settings.

This is hard to work with. While adjusting the Renderman cone settings while IPR is running, I can nicely watch the settings being updated in IPR. But the settings I decided on, will never be used in the final rendering.

I suggest to ditch the Blender cone settings tab all together.

Cheers,
Andreas

How do I fix this?

In RFM this does a few things, lets you select by ID, and do crop windows for IPR,

Here is a material node setup:
PxrTexture -> PxrDiffuse -> PRMan Material

This basic setup works very well.

Now, if I wrap PxrDiffuse within a node group (PxrTexture -> Group -> PRMan Material),
the image texture is not taken into account anymore.

Also I set a red diffuse color, Suzanne is gray in this case:

Few checks:

• If I unplug the texture from the group node and set manually a color, the color is not taken into account.
• If I force the color of the PxrDiffuse in the group (unpluging the input node), the color is set properly.

I have tried several things, but each time I am trying to factorize with a group, the input seems not to be taken into account. I am missing something?

Thanks a lot

accents and such for object names screw up RenderMan. There are a bunch of places they would need to change but we could substitute blanks for them.
