We have released CentiLeo for Cinema 4D 0.43.

This long time we were working on performance, bugfixes, interface, stability and a couple of features. From now on we will divide the work better and release new versions with less delays.
This is a list of changes
[core] CUDA 8 support. NVIDIA Pascal GPUs should be supported.
[core] Reworked render algorithm. Now it is progressive/bucket which on the first render iteration shows the entire Beauty pass and for any subsequent render iteration it computes Beauty pass and all enabled AOVs in parallel using buckets.
[core] One render iteration (“Iter” in IPR) now means one render over entire image with guarantee that every pixel received several samples. Before 0.43 the single render iteration stochastically fired up to one million samples over entire image (and it could lead to significant noise for large resolution images). The new sampling layout of 0.43 which is automatic and adaptive leads to significant noise reduction.
[core] New AOVs: Environment, Reflection1, Reflection2, Base, Transmission, Emitters. Now up to 16 AOVs can be computed in one render process in parallel with negligible (<5%) compute overhead. All this works also in IPR mode same way.
[core] Alpha channel support added.
[core] 15% faster render iteration computation in general.
[core] 3x faster render convergence for image parts with materials with several enabled layers like: multi-material, reflections+diffuse, reflections+transmission, reflections+diffuse+SSS. For example: glass with reflections, glossy and carpaint implementations are rendered much faster.
[core] All layers of material (reflections, diffuse, transmission, SSS are combined based on weights that are relative to each other). So all the layers have equal rights inside material. Stack-based policy is removed.
[core] Faster render convergence for shadow regions (perceptually2x faster).
[core] Rendering large resolution images like 4K or 10K is 30-50% faster.
[core] Render limitations are introduced for robustness. They are indicated in IPR window. For example, smallest GPUs with 1.5-2GB memory support 30-50M polygons and 100K mesh instances. GPUs with 3-4GB+ memory support 250-400M polygons and 1M mesh instances. These limitations will be further pushed forward.
[core] Bugfix: now render can work with at least 896MB of provided GPU memory by OS/driver. This low memory budget may be available on 1.5-2GB GPUs attached to display. Switching off other GPU applications may increase available memory for renderer.
[core] Bugfix: now environment map not blurred if seen through the glass.
[core] Bugfix: now absorption renders correctly.
[core] Bugfix: fixed rare overflow problems with complex shadows.
[IPR] IPR priority is introduced (see in render settings -> IPR). Larger priority increases render speed (samples/sec indicator) but can make GUI lags. Lower priority decreases render speed by 10-20% but makes work with GUI much smoother.
[IPR] Separate render resolution setting for IPR (see render settings -> IPR).
[IPR] Render region support.
[IPR] Render pause/resume.
[IPR] Render camera lock.
[IPR] Render enable/disable automatic scene updates.
[IPR] Full scene reload button.
[C4D plugin] Large usability rework of CentiLeo materials GUI. Now can unroll attached textures right in material editor. Now can reach the editor of selected texture from material editor in one click. Now can drag&drop textures among different material properties.
[C4D plugin] Can transfer all IPR currently rendered images (in HDR mode) to Picture Viewer (push the left-most button in IPR window).
[C4D plugin] Scene copying and reloading is avoided if IPR is already running and user clicks to Cinema 4D render to Picture Viewer or render to viewport or render region.
[C4D plugin] Bugfix: material preview renders even with running IPR.
[C4D plugin] Bugfix: various problems fixed when IPR and/or Picture Viewer render are enabled.
[C4D plugin] Bugfix: various problems fixed which forced IPR render resets when expression tags are available.
[C4D plugin] Bugfix: CentiLeo material preview renders even with running IPR.
[C4D plugin] Bugfix: right side material layer toggles now have effect on render and are animatable.
Known issues to be solved
- No yet multi-GPU
- Need texture/shader copy-paste (and copy-paste as instance) across different materials.
- Need to fix problems with texture paths using “preset…” using native Cinema 4D bitmap procedures.
- Sometimes GUI of IPR window may have old style controls.
- May not initialize if AMD GPU is in your computer together with NVIDIA GPU.
- Very limited scene converter tool from Cinema 4D native materials (only diffuse color and texture are converted and translated if assigned to the object)
