I´m making some vegetation test in corona. Hope you like it and give me some valuable tips to improve.
Trees and bushes are made using GrowFx plugin, these trees are a MidPoly versions to use in mid/far range, no metamesh/displacement, i need to improve them. When i try to use the HightPoly ones i get out of RAM. I made this images to test the trees and learn Corona. The scene is far from finish but i just want a fast vegetation test.
Render times 8-12h using HDRi, but they need more to get clean noise (i just don´t have the time). I have some problems in order to get clean results in this particular scene. Albedo looks ok, i disable all opacity/normal maps from trees, low albedos, hide glass/curtains, etc. Bucket mode give me the best results so far but takes a lot of time. PT+PT and PT+HD both give me noisy DOF or fireflies (even 400+ passes). Ray count its around 1mill (usually y get more. I7 3770K). I think the main problems is the rays going through so many trees and low glossy wood on the house. I´m very new to Corona, so i´m making something wrong for sure.
Rewalanche. I make some tests using GI/AA 4 but even for 400+ passes the wood looks noisy. Using bucket GI/AA 8 and 4 initial passes i get clean results at 9/10, ¿if i let PT+PT run for more time i will get cleaner glossy reflections?. For the ones without DOF y use PT+PT.
romullus. I think you are right, the reflections are to strong. Thx
Juraj. Here is the material for the leafs, to be honest i think it could be much more realistic if i put more work on it, but its ok for mid/far range trees. I end disabling alpha/Normal map in the final renders. The trees have vertex color so i blend 2 different materials (dark green/light green). Textures are from Xoio i can´t find any birch where i´m living now.
This is pure awesomeness. The look of foliage and the DoF shape reminds me of pictures I took some time ago with a soviet FED 5B camera. Such works must make Keymaster and the whole Corona team proud of their child.
reminds me of alex roman. love the wood reflection and the simplicity of the structure.
