Re: Transitioning from VRay to LuxCoreRender

I tried to adjust IOR, leaving other parameters intact, but it seems to be quite different from VRay's setting (i.e. with the same IOR the render is quite different). LuxCoreRender use physical correct IOR means c_in material/c_in vacuum, c is speed of light. If you like correct simulations, define...

Suzannes Wave

One frame took 3m10s, 300 samples per pixel, for the array of 900 Suzannes. Enjoy the short animated GIFs after clicking on their image. Suzannes-Wave.gif There are really lots of Suzannes, see. Suzannes-Wave,-zoomed.gif During the last days I revised the code of the Rainbow Chains V0.6 script, remo...

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

in the hybrid render caustics are not reflected on the cube. is this is the normal behaviour ? This is a good question. Looks like BiDir behavior. BiDir does not mirror everything, e.g. scattered laser beams, it looks like BiDir only renders with max depth of one in these cases. Is there any good r...

Backwards Ray Tracing, a thought experiment

Backwards ray tracing (= LuxCoreRender path) If backwards ray tracing means tracing from camera sensor area to lights I wonder about how this is done practically. Thought experiment Cases rays in any directions from a randomly picked sensor pixel to the scene within per camera optics defined sphere ...

Rainbow Chains V0.6, Interactive Blender Fun Script

Since first post of Rainbow Chains V0.1 I have revised and extended the script as described in a former post. There are several classes and methods containing all the data and logic. Three classes get registered the others are used to initiate some objects on main level of the script. If layout prop...

volume cache requires implementation of path depth>0

It's already part of indirect cache! :D I have yet to test it and even don't know how to activate it :? I have yet to test it and even don't know how to activate it It's in the volume output node (only visible if cache is enabled). Thank you for the remember. I recognized Dade's picture. Indeed the...

Re: PhotonGI cache

I'd suggest that hybrid path tracing gets abandoned here and instead caustic cache updating is done continuously on CPU and at the same time path tracing on the GPU for the specified step number and then waiting until the next cache update is ready (or vice versa if the sampling takes longer in cas...

A nice answer to this RTX things From here : https://corona-renderer.com/forum/index ... c=21433.30
That is interesting to know. RTX support would not help much in a lot of rendering situations.

Re: RTX Vulkan OCL 2.0 INTEL AMD GPU IA

It only gets interesting with 2080 and nvlink, 22gb vram is something that could be worth it. I'd still like to see some good out of core on luxcore though. Maybe some smart proxy system or idk... I wonder why Nvidia didn't go with the VEGA like native shared Memory system ? Did you look at the tra...
