Re: ENV cache problems

Sadly persistence only solves one issue still.. 1.Heavily obstructed exterior(dense foliage for example) will result in pretty bad cache which might need different settings (more ram more preproces) 2.Preproces and ram usage is also varying depending on camera position (autolookup radius isn't expo...

Working correctly now. Quick comparison gif: https://i.imgur.com/jN9hZyZ.gif Note: The difference in rendered image be...

Re: Emission Unit Artistic/Power

The reason why it gets brighter when using Power is that now a bug in BlendLuxCore has been fixed to make Power work the way it was always supposed to be in LuxRender.

Re: Triplanar mapping / stochastic texturing

Here... This is a WebGL implementation of Histogram-preserving Blending for Randomized Texture Tiling . This method allows you to take any input texture and produce an infinite, non-repeating texture from it. The method is fast, simple, requires minimal preprocessing and storage, and the input textu...
