Available CentiLeo 0.53 for 3ds Max 2014-2018!
We have updated CentiLeo material system completely. The GUI and settings remain the same but the models of reflections, refractions, SSS, absorptions have all been updated to improve the quality and paramter response.
E.g. SSS have become correct and 10x faster (not a big deal because it was very slow before). But now it looks like diffuse if subsurdace scatter radius = 0 and shows logical behavior when increase the radiuses and combine the channels.
We have also intelligently killed the fireflies that could be seen through several glossy-glossy surface reflections using much smarter new GI Clamp algorithm.
Change Log: cntlmax 0.530 alpha (2017 November 20)
[core] Subsurface Scattering is correct now and has 10x faster noise reduction due to improved maths. The speed of SSS is close to diffuse. Same as before it is based on 3 layers.
[core] GGX anisotropic reflections and refractions. Better looking highlights and fast. Some old scenes with rough reflections may seem to render slower 5-10%, but this is due to different look and changed highlights, the speed isn’t really degraded.
[core] Faster (less noisy) rough glass and shadows under rough glass due to better maths.
[core] Fixed Absorption parameters. They now affect transmissive and translucent objects and also their shadows.
[core] Improved quality of GI Clamp params. They now preserve glossy highlights better and kill the hotspots a lot smarter while keeping the highlights. Default GI Clamp values of 10 are very good if final post production image exposure is 0.
[core] Added “Expected Exposure” parameter that should be similar to the post production planned exposure. This is useful in cases when the lighting is very low in the scene and then user compensates it increasing the post exposure. In this case to make GI Clamp params and noise detector more efficient just set Expected Exposure similar to Post Exposure (+-1). Efficiently tuned GI Clamp and Noise detector may accelerate image rendering.
Known issues to be solved
- May not initialize if AMD GPU is in your computer together with NVIDIA GPU.
- Very limited scene converter tool from other renderers (only diffuse property and textures from Standard material and Vray material)
- UVW mapping change of parameters may not be accounted by IPR scene auto update mode. To be solved.
We are currently using JUCE library (
If everything works well on main technical side then we will buy the full license of JUCE and get rid of these small issues.
Please, install modern NVIDIA display drivers. E.g. at least 372.70 or one of the newest.
Adjust GPU Rendering Low-priority settings
Can be found in CentiLeo Renderer Settings -> Hardware Settings.
Low-priority flags are ON by default in IPR mode for ALL GPUs. For fluent work in IPR mode it’s HIGHLY RECOMMENDED to keep enabled “low-priority” setting for DISPLAY GPU and switch if OFF for other render GPUs which are not connected to the monitor. Low-priority option is useful for display GPU because it is used to display the elements and models of 3D Viewport and OS.
If you have many GPUs in one computer then Display GPU can be excluded from IPR render to have less competition between Viewport and CentiLeo for Display GPU, this can improve the system feedback overall.
Pls, make the tests and send us feedback!
