On question.
I have a loop that checks session->HasDone()
Do I have to call session->Stop() when the render ends and HasDone() returns true?

Hi Guys, I have a strange issue. We are trying to render an animation. For some reason some of the frames have low sample level. I will explain in detail. I load the whole scene. I set the camera position for current frame. I set desired sample level in session config and start render. I can see the...

Hi guys. Finally I've found the solution. The ray that is passed to Embree library has Nan in origin and direction. That makes embree library scan all geometry. So the solution is to add: if (isnan(ray->o.x) || isnan(ray->o.y) || isnan(ray->o.z) || isnan(ray->d.x) || isnan(ray->d.y) || isnan(ray->d....

First of all I wanted to say that I have recompiled luxcore with embree 4.2. It doesn't change anything with my issue. I want to show you a short video that shows the problem. https://we.tl/t-HRjU1pQohr At the beginning of the video, I move the camera and I can see the result of render in few second...

Hi guys, could anyone help? I still have an empty render. Embree rtcIntersects1 function returns an empty result (nothing is hit). I've check all parameters and don't know what to do. I have found that RTCIntersectsArguments should be initialized so I call: rtcInitIntersectArguments(&intersectAr...

I have recompiled luxcore with Embree 4.2 but for some reason render is completely empty. I can see only background image. I think the ray does not hit any geometry. To compile with Embree 4.2 I've mede following changes: diff --git a/src/luxrays/accelerators/embreeaccel.cpp b/src/luxrays/accelerato...

I have found that the function Scene::Intersect takes all this time. In our case, CPU use, all this time is taken by EmbreeAccel::Intersect. This scene has 8000 instances of a tree. So it looks that if the ray hits this tree layer, it stuck for 1-3 minutes. I'm trying to find out if updating embree ...

currently I'm analyzing bidircputhread.cpp and it looks that the problem is somewhere here: if (boost::this_thread::interruption_requested()) SLG_LOG("[BiDirCPURenderThread::" << threadIndex << "] 5b"); if (!eyeVertex.bsdf.IsDelta()) { for (vector<PathVertexVM>::const_iterator li...

Hi Guys, we are using luxcore for quite long time. We have found, that sometimes luxcore hangs when calling BeginSceneEdit(). Now we have a scene, that makes luxcore block each time. So we have following situation. The render starts. We are using live session, so we can see that everything looks ok....
