Yup, of course. That would be great. And yeah, the core looks great, I was just making some observations. Overall though, keep up the good work Nadro!

Please post here not only patch but the patched files (.h, .cpp) too. I have some troubles with patching. Or mail it to me please (naxart@gmail.com).

Thanks.

hi everyone , i'm new to irrlicht , i have successfully implemented Occlusion Culling in my irrlicht program. But what is the problem is " Occlusion culling also preventing SHADOWS to be projected". i.e Occluded Object's Shadows are not visible. Occlusion Culling disabling Occluded Objects for DEPTH TEST. So what i need is to disable Occlusion Culling during DEPTH PASS to shader . Is it Possible to Disable Occlusion Culling for particular pass ? or Is It Possible to Disable Occlusion Culling in Particular Camera's View ?

Well, teh occlusion query just returns a value to you, which says whether pixels where written or not. What you do with that value is up to you.

was wondering how this turned out if it ever made it into irrlicht 1.8 mentions https://sourceforge.net/p/irrlicht/feature-requests/54/.

It did but internally its a shitty map of <Node,OcclusionMesh> which does a search (linear I believe!) on an array of pairs which if you have 1000 nodes.. results in 25% of your CPU time in a N^2 search
