CentiLeo 0.54 for 3ds Max 2014-2018 is ready! Quality becomes better! Bump is much better, however the majority of time was spent on glass+liquid correct IOR handling.

Change Log: cntlmax 0.541 alpha (2017 December 25)
[cntlmax] Fixed various cntlLight bugs (bad GUI when create several lights, not working size of rollout, wrong radius export for spot and sphere shapes).
[cntlmax] Fixed crashing bugs in cntlProxy when input non ”.cntlproxy” files.
[cntlmax] Fixed some export bugs for instancing and Max Compound Scatter objects.
[cntlmax] Fixed IPR bugs not receiving keyboard input for post processing controls.
Change Log: cntlmax 0.540 alpha (2017 December 18)
[core] Support nested Transmissive refractive objects with different IOR (e.g. liquid in a glass with ice cubes inside). A liquid object geometry must overlap slightly the glass (same as in other modern renderers). The material of liquid object must enable the flag “Is Liquid” (available in cntlMaterial->Transmission menu). Same works with water droplets on the bottle or any other liquid objects that are modeled inside or outside a glass with slight geometry overlapping. This way all relative IORs between refractive mediums will be computed correctly internally.
[core] Added procedural Dirt shader which can enable different colors and material properties on crevices, convex and concave geometry regions. Occluded, Unoccluded and Distance parameters can be textured. Dirt shader can be nested into other Dirt shader.
[core] Fixed bump mapping “terminator” artifacts that can be visible on lowpoly objects and lit by small area light source. User can tune the effect of this fix with “Light Shift” parameter which is available in cntlMaterial->Bump menu for Cinema 4D and in cntlMaterial->Common for 3ds Max. This works for all material properties (diffuse, reflections, etc.).
[core] Fixed reflection artifacts on low poly geometry where smooth normals differ too much from real normals of geometry.
[core] Fixed reflection loss of energy when combined with other material properties such as diffuse or SSS.
[core] Fixed SSS color and weight automatic normalization.
[core] For easy handling in cntlBitmap there is no need to select type of texture “image”, “b/w bump” or “normal map”. This is resolved automatically, except for normal maps where user must enable “Is Normal Map” flag.
[core] Added option “Output Alpha channel” to cntlBitmap. Useful for application with PNG and cntlMaterial->Alpha channel.
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.
Please test and report about any issues in this pack.
