None.

BTW, epsilon change to a new value (i.e. never used before) causes a kernel recompilation when rendering on GPUs.

"target = position + direction" where target is a point, position is a point and direction is a vector (the length of the vector doesn't matter).

	viewPort.GetAffineTM(aTM);
	Point3 viewDir = coordSysTM.GetRow(2);
	Point3 viewPos = coordSysTM.GetRow(3);
	gw->getCameraMatrix(mat, &invTM, &persp, &hither, &yon);

	Point3 viewTarget = viewPos - viewDir;

more than 3000 passes and no issue. I'll try to upload a new build by the weekend. if any problem persists, you need to provide me a scene that shows the issue.

such schematic views are great for project renderings. if you manage to add it then chapeau

May I ask if you meanwhile can release a new build with this latest fix and instance support?

I'm a little bit busy on a project this week and I think you need to wait until next weekend so I can manage to release a new build. Also, clean up and upload new code to GitHub.
Sorry for that but there is a problem with special characters like "é" from other languages that can affect the instancing object that I need to fix. it is not a big deal but it is a little bit heavy process to rename all objects always before render and I'm trying to find a better solution.
In the meanwhile, I manage to fix the problem with rotate, scale and modifying the instance objects and that's a piece of good news.
