Follyx Posted August 28, 2017 Share Posted August 28, 2017 (edited) any news about the annoying bug? i.e. popgrain solver: if activate "use Open CL" than this message appear: Unable to load HFS OpenCL platform. edit: works on linux, not on windows Edited August 28, 2017 by Follyx Quote Link to comment Share on other sites More sharing options...
blaykenadeau Posted August 31, 2017 Share Posted August 31, 2017 I had this error when using Flip/Grains. It turned out opencl was using my integrated graphics instead of my actual GPU. You can check in Help --> About Houdini --> Show Details. Look for OpenCL Platform, and then OpenCL Device. Quote Link to comment Share on other sites More sharing options...
Follyx Posted September 9, 2017 Author Share Posted September 9, 2017 Yep but that isnt a solution for the problem, is it? Quote Link to comment Share on other sites More sharing options...
Guest tar Posted September 9, 2017 Share Posted September 9, 2017 We can only guess because you aren't supplying any hardware details. Either you should use the cpu or a discrete GPU for the OpenCL. So put either of these into your env file: HOUDINI_OCL_DEVICETYPE=CPU HOUDINI_OCL_DEVICENUMBER=1 if that doesn't help then use hgpuinfo -l to list all the available OpenCL devices.

Hopefully anyone could help me know. Ah and thats a laptop. Its a dualboot. On Linux there are no problems. Just in Windows. And since its a system with 2 graphics I can decide for different software wich card I want to use. Quiet normal. But is there an executable for OCL? Never heard about it, but maybe... Houdini works with the Nvidia. But not OCL... Edited September 11, 2017 by Follyx Quote Link to comment Share on other sites More sharing options...
