LuxCoreRender Forums

Thanks! I got it to work, that is blender didn't crash and managed to find the "render engine selection" drop down....after that haven't a clue what is going on, think a render was started but Luxcorerender didn't open...can't find any instructions on how to operate this in either the lux...

I don't know the macOS situation in detail, but it seems like the binaries need to be signed for macOS to execute them, which they currently aren't.
Apparently you can run them if you disable "SIP" even in their current non-signed state.

Ah, got it: After applying the negative scale, it is necessary to recalculate the normals.

I couldn't find the source of the problem yet. The only thing that seems suspicious to me is that some of the objects have negative scales. When I apply the scale on these objects, the viewport render looks like the final render (so both show the problem of the missing light beams). However, I could...

World position.

PhotonGI on volumes is now disabled by default. Warnings are shown if a volume with enabled PhotonGI is used as world volume.

I can do that.
Maybe it would also be a good idea to set the "Use PhotonGI Cache" checkbox on volumes to disabled by default?

The lower panel is from Cycles, it was not properly hidden in v2.2. This is fixed now as of v2.3beta2.

By the way, since ray epsilon is still a kernel parameter, I guess I have to pass the default min/max epsilon in BlendLuxCore to KernelCacheFill()?

I could add a dedicated function (however calling KernelCacheFill() when the cache is already filled takes no time).

It would be good so I know when I have to show the message and when not.
