System Information
Windows 7 Professional
Cpu: i5-3470
gpu: gtx 970 4gb

Blender Version
Broken: (example: 2.73 (b4d8fb5)
Worked: (unknown)

Short description of error
When using the displacement method of "True" and using a bump map in the node setup (using cpu and experimental) it crashes every time on render no matter how low or high the resolution of the mesh is.

Exact steps for others to reproduce the error
Open Blender 2.73>add a mesh>create a node setup with displacement>turn on cpu rendering> turn on experimental>enable "true" displacement method under
object data panel for your mesh> Render with either real time or f12> watch blender crash :(

The bug as been fixed a working version of blender can be found here https://builder.blender.org/download/

This fix will probably make it into 2.73a

You may have to wait for tomorrow for the fix to be implemented

@MasonMenzies you don't have know what the code change means

Mason commented

2015-01-19 18:22:58 +01:00

so what your saying is it's been seen as a bug and will be fixed in the next build?

Aaron Carlisle commented

2015-01-19 18:26:19 +01:00

Yes tomorrow Build bot version will contain the fix and it might already be in there if i am looking at the build times correctly

Mason commented

2015-01-19 18:27:34 +01:00

wow, really? that's awesome! well thanks guys for sorting that out :)

Mason commented

2015-01-20 02:31:42 +01:00

does anyone know if the fix has been posted up yet? i downloaded the latest build (the page said it was updated today) but it's still crashing. anyone know if it is up?

Bastien Montagne commented

Buildbot builds are built once a day (usually during european night), the one done this night should have the fix, the previous one probably didn’t…

The latest builds which are a1f4821 should have the fix included. I also downloaded the build and can't reproduce the crash.
