BMW 8 - Caustic + Dispersion experiments
Posted: Mon Dec 30, 2019 7:40 pm
Hi there!
I'm Pablo and I've been doing the switch from 3ds max to the open-source blender universe for about a year approx.
While trying blender, I bumped with this amazing render engine and I decided to try it and test its capabilities. I've been playing with it and below you will find some renders I've done.
However, I want to learn more about it! I've encountered some things that I will thank you if you can help me understand how I can solve them better.
- The first thing that I noticed is that after the denoising process the image kinda looks blurry and some details get lost. I mainly trying to enhance some details like the tire sidewall and the carbon fiber bump textures.
For the image of the BMW with the purple background I used 800 samples, Bi-dir (metropolis) engine, 1,25 px as the filter width and even though the final render is at 1920 x 1080 I rendered it at 2400x1350 to see if the resolution is the cause, but it wasn't. It took 1h 10m to render it. Should I try increasing the samples and deactivate the denoiser? How many samples should I try? Should I consider other parameter to make a sharper image? This kind of blurriness also happens at close-ups. (Image A)

- Apart from that, I've noticed that if I use a cycles material it doesn't render/show properly (Image B). You will find that I'm trying to create a carbon fiber texture. The pattern repetition doesn't match and the bump strength does not have any effect. It doesn't work either in 2.80 nor 2.81. Are cycles materials that incompatible? The only reason why I'm using that as a cycles material is that the cycle nodes offer the "Box" mapping option with the "Blend" parameter which is very handy for this kind of textures and I couldn't find anything similar in the Luxcore nodes. Is this kind of option available in this render engine?
____
Finally, I think that I found a general bug.
If I apply a material I have to move from render mode to solid view and go back to render mode to refresh the applied materials to the objects to the scene. If I don't do that after applying a material, it will look like nothing has changed. Sometimes it also happens when doing major changes in with the material nodes.
Thank you in advance for any critic and info you can provide me!
Here I will leave a link to my artstation porfolio if you are interested
