HDRI Testing

[Dade]

I can reproduce the problem too, on Windows. It was and out of bound memory access due to the size of a memory copy. The size was expressed in bytes instead of float so the amount of memory copied was effectively 4x the right size. 3/4 of the copied memory was landing out of intended region.
On large HDR this memory region was effectively out of the allocated memory and was triggering a memory fault on Windows.

This affect all OpenCL render engines when using an infinite light and/or, in same rare case, a pixel filter. This problem has always been there, it is not something new introduced recently (it strange no one ever noticed).

I have attached a fixed pyluxcore.pyd (with OpenCL support) file to this message, unpack the .zip and replace the one in your installation and it should fix the problem.

hi, Dade
tested with the attached pyluxcore.pyd and i still get what it looks like the same crashes (even on a fresh scene)...

BTW
can't get blender console to stay open (--debug-all) or generate the error log with Lux (how to?, used to be options available)
win7 x64

Edit:
also when using "Only Write LuxCore scene" error appears:

Code: Select all

Undefined property in Properties::Get(): renderengine.type

Edit2:
Strange thing. OCL+path starts to render fine after CPU+bidir is used.
While on the other hand, renders fine with CPU+path, but after switching to OCL+path it starts crashing again.
All these with new pyluxcore.pyd used

This is something I have already seen once, I'm not sure when it happens, it may happen when you export a scene multiple times and/or switch from binary to text format

Ok, I have found a second problem like the first one. The pyluxcore.pyd attached to this message doesn't seem to crash anymore.

Yes! Same experience here No more crashes. Thank you!

Thank you, working fine now. No crashes.
I replaced the file.

It may be worth to release another alpha very soon to just have this fix generally available

Very good idea . can speed up testing also

Going to pack alpha4.
