Hello, I got some issues displaying geometry in shaded mode in the viewport in H14. In wireframe mode I can see the geometry as expected. But as soon as I press “w” to switch into shaded mode the geometry disappears entirely.

Via the environment variable HOUDINI_OGL_DUMP_SHADER_ERRORS I got the following error message:

Geometry shader compile:
0:5(12): warning: extension `GL_EXT_gpu_shader4' unsupported in geometry shader
LINK:
FS compile failed: bad cond code

Mesa 10.1.3 implementation error: Failed to compile fragment shader: FS compile failed: bad cond code

My system:

Linux Mint 17.2
No dedicated graphics card
CPU: i7-4790K with Intel HD4600 graphics
MESA driver: 10.1.3 (current version for Linux Mint 17.2)

Btw, I had similar problems with H14 under Windows 7 with the latest graphics drivers from Intel.

Any solution for this?

Thanks!

Your graphics card does not meet the minimum requirements. Just get used to the viewport being a proxy for render. Or switch to the ipr Render View.

Thanks. But at the “Graphics Hardware Requirements” page the Intel graphics HD 4600 is listed as supported for H14. So I think it should work.

What do you mean by “switch to the ipr Render View”? How do I do this?

Hm, wish I knew what “Bad Code Bond” meant. It's failing to compile the fragment shader for some reason. I guess the error must make sense to Mesa developers, but it doesn't tell me anything about what code is causing the failure.

Thanks for your reply. Meanwhile I found a solution. I updated the MESA driver to version 10.3.0 directly from 01.org. Now it works fine for me.
Maybe there is a bug in the current MESA version 10.1.3 delivered with Linux Mint 17.2.

That's good. The message was probably some sort of internal compiler error that the Mesa team has resolved.

I am new to Linux and just installed Houdini 15.0.244.16 (production build) on Mint. Running into the same problems No geometry visible in shaded mode.

So far I downloaded mesa-11.0.5.tar.xz from ftp//ftp.freedesktop.org/pub/mesa/ and extracted it. Is this the correct one?

If so, how can I update a MESA driver?
