Hi there!,

I work with blender and I'm trying to use openCL for Cycles rendering, but it's not activated by default. I created a new item on "KDE Menu Editor" but I don't how to specify custom commands to it. Here's how it looks:



How do I specify a custom command after it's path, like "CYCLES_OPENCL_TEST=true" for example?

R9 270X (14.12 drivers)
openSUSE 13.2 x86_64
KDE 4.14.6

Regards,
Amarildo

Someone, pretty pretty please?

what happens when you just append the options to the command string?

in advanced options check "Run in terminal" do errors show?

wait is that an environmental variable or a blender option?

if env try:

Code: Select all

export CYCLES_OPENCL_TEST=true; blender

Hmm, I tried every possibility, with no dice. OpenCL just doesn't seem to work. It works if I launch Blender via Terminal though.

try

Code: Select all

CYCLES_OPENCL_TEST=true blender

found that here http://www.blenderartists.org/forum/sho ... -maybe-ATI)

Since this looks like an environment variable:

Code: Select all

env CYCLES_OPENCL_TEST=true /path/to/blender --some parameter

The "CYCLES_OPENCL_TEST=true" assignment is a bash "trick", it doesn't work with rather plain (most non-interactive, even some interactive) shell interpreters.

Looks like it's not going to work. Here are all the 'command' lines I tried:

Thank you guys for trying to help me. Have a nice easter holiday you all.

Code: Select all

env CYCLES_OPENCL_TEST=true /home/amarildo/Documents/Programas/blender-2.73a-linux-glibc211-x86_64/blender

the basic command is "env", it sets the environment variable (that is NOT a parameter!!!) CYCLES_OPENCL_TEST=true and then calls blender.

(blender will at some point then call getenv("CYCLES_OPENCL_TEST") and check whether that is "true")

You're right, luebking! I though the path to Blender had to come first, excuse my ignorance
I pasted your code line and now it works! Thank you very much, and thank you 'google01103' too for the effort You guys are the best.

Best wishes,
