VRayMtl improvements in the 3ds Max viewports (WIP) Vladimir Koylazov 2021-01-15 | A WIP demo of the improvements we've done for the viewport representation of the VRayMtl material in 3ds Max 2021.
Firefly removal algorithm in V-Ray 7 Vladimir Koylazov 2024-10-01 | This video demonstrates the effect of the firefly removal algorithm in V-Ray 7 in a situation that has been traditionally very challenging to render - reflections of small bright light sources in glass objects. These typically require a lot of samples to get them stable in animation. In V-Ray 7, the firefly removal option makes the animation a lot more stable by removing the flickering highlights without affecting the rest of the image.For more information and to join the V-Ray 7 public beta, visit chaos.com/vray/3ds-max/beta-version-7
Rendering Gaussian splats with V-Ray: another test Vladimir Koylazov 2024-09-30 | This is another test of rendering Gaussian splats with V-Ray. The splats were created with PostShot out of drone video footage of the city of Hanoi from this site: pexels.com/search/videos/drone%20city The camera poses were resolved with Reality Capture as it turned out to be much faster and more precise at this compared to PostShot.Rendering of Gaussian splats is now available in the beta version of V-Ray 7 for 3ds Max: chaos.com/vray/3ds-max/beta-version-7
Raytracing of Gaussian splats with V-Ray Vladimir Koylazov 2024-09-02 | This video shows an experimental implementation of raytracing of Gaussian splats in V-Ray. We can get correct raytraced camera effects like motion blur, DoF and distortion, as well as proper interaction with other CG elements in the scene - reflections, refractions and matte/shadow surfaces. The implementation works with Gaussian splats .ply files produced by other popular tools like PostShot, Polycam, Luma.ai, Kiri, nerfStudio etc. Gaussian splats can be used as extended scene environments or to represent individual objects in the scene.

Win32 vs Qt UI in 3ds Max Vladimir Koylazov 2021-06-19 | We are gradually rewriting the interface components of V-Ray for 3ds Max in Qt. Here we are comparing the UI drawing speed of the VRayALSurfaceMtl material with Win32 (left) and Qt UI (right).
Cosmos field Vladimir Koylazov 2021-02-23 | A quick experiment with assets from Chaos Cosmos; everything is from Cosmos including the HDRI. The grass and flowers are scattered with Corona Scatter. Rendered in V-Ray 5.1 while testing the new release. IMHO not too bad for a non-artist like me 😃
Integration of VRayScatterVolume in VRayMtl Vladimir Koylazov 2021-01-15 | Experiments with integrating VRayScatterVolume as the translucency component of the VRayMtl material.The original video has somewhat better compression:drive.google.com/file/d/1lcVtomeMqqQDCrjMNLvx2mnXRRV-aYUs/view?usp=sharing
Optimizing multiple scattering for VRayVolumeGrid Vladimir Koylazov 2020-07-19 | Some results from optimizing raytraced multiple scattering inside VRayVolumeGrid. Render time is ~2m 16s on a Threadripper 3990X. The cloud is an OpenVDB file from the Disney Moana island scene: technology.disneyanimation.com/clouds (not the full OpenVDB resolution though, still have to let that render).
Running Lavina through eGPU Vladimir Koylazov 2019-03-06 | Surprisingly, running Lavina on my laptop through eGPU seems to work fine - althrough there is slight frame rate drop compared to running it natively on a workstation with the same card.
10,000 VRayLights with V-Ray Next, Update 2 Vladimir Koylazov 2019-02-12 | V-Ray Next, Update 2 will include improvements for scenes with many lights sources (thousands of them):*) Faster light cache for scenes with many light sources; sometimes up to 2x times faster (for a test scene with 5000 lights);*) Better algorithm for discovering important light sources greatly reduces the probability for flickering with the adaptive lights;*) Faster BF+BF rendering when the adaptive lights are not available.For this scene, the render time on a Ryzen Threadripper 2990WX was approximately 6 minutes per frame, with the V-Ray denoiser applied on the final sequence.

V-Ray denoiser plugin for Nuke WIP Vladimir Koylazov 2016-07-23 | Coming soon - we worked on a Nuke node that implements the V-Ray denoiser natively inside Nuke. The plugin is free and separate from V-Ray for Nuke and can be used on its own.Many thanks to our V-Ray for Nuke devs who gave their time to code it!
V-Ray production renderer in IPR mode WIP video 3 Vladimir Koylazov 2016-07-20 | This is the third video for my progress of turning the production V-Ray renderer into an IPR renderer. Added a button in the V-Ray VFB for start/refresh of the IPR render.
Rendering from V-Ray RT to an Oculus Rift Vladimir Koylazov 2016-06-22 | Some R&D that we've been doing recently - rendering a 6x1 (stereo) cube panorama from 3ds Max directly to an Oculus Rift. An nVidia VCA would have come in handy for this... I'm still not sure if this will end up in V-Ray, but if you would like to give it a try, let me know.

V-Ray sampling tutorial Vladimir Koylazov 2015-07-21 | My current favourite way of setting up V-Ray sampling. The video was recorded in 3ds Max and V-Ray 3.2 for 3ds Max, but is valid for any other V-Ray 3.x integration (i.e. Maya, Modo, Katana etc)
Stochastic flakes Vladimir Koylazov 2015-07-01 | Asen has been working on implementing a stochastic flakes material based on a paper from last year's Siggraph. It turned out that quite a few changes are needed to make the algorithm usable in practice.

More experiments with VRayScatterVolumeMtl Vladimir Koylazov 2015-02-16 | Turns out I had a bug that caused the light cache to not be used to the full possible extent. Once I fixed it, the material renders smoother and a lot faster.This example uses a slightly anisotropic phase function (0.3) to give the material a watery appearance.
VRay2SidedMtl stack of paper Vladimir Koylazov 2014-11-09 | In this video I animated the translucency value of a VRay2SidedMtl applied on a stack of planes. It is interesting how higher translucency values make the paper look more thin and greasy.
Hair in V-Ray RT GPU Vladimir Koylazov 2014-10-17 | Goofing around with a (very) early version of hair support in V-Ray RT GPU on two GTX 980's
Testing the implementation of VRayFastSSS2 on the GPU Vladimir Koylazov 2014-09-20 | This is an early test of the implementation of VRayFastSSS2 material for V-Ray RT GPU.Quite unfortunately, YouTube's compression completely kills the quality in the dark regions.The model is free from Infinite Realities: http://ir-ltd.net
How to create a dome camera in V-Ray for Nuke Vladimir Koylazov 2014-09-10 | This short video shows how to use the Python post-translate callback in V-Ray for Nuke to render with a dome camera.
Rendering with the light cache on the GPU Vladimir Koylazov 2014-09-08 | This is a test of rendering with the light cache on the GPU. The light cache itself was precalculated in fly-through mode on the CPU.Unfortunately the final colors and quality of the video have nothing to do with the actual renders - I don't know why the video comes out all washed out and blurry.
