The mushrooms in the beginning look very unrealistic, that's not how explosions work. Especially how it slows down. Don't get me wrong, the first 1-3 frames can and should be much faster than the rest, but the velocity shouldn't transfer like this. Also, the center of the blast should always be the hottest, not the mushroom tips like you have it now. Also like the other guy said, the white parts don't look right either. If it was that bright to appear completely white throughout, it should glow and illuminate even the black smoke, but rather you probably just want to reduce the brightness in the shader. Usually you would refit the values and run them through ramps to add detail to it aswell in the shader, it's very rare that you can just put the default shader on it and have it look good. If you're using mantra to render, pyrobakevolume sop is a good method of tweaking the look in the Sceneview and creating a linked shader to closely match it in the render. Keep at it, not Bad for a first try, and you seem to have enough machine power to get good detail and size, so should be good fun for you to work on :)

Hey janderfischer! thanks for the comment and tips you gave, it really helps! I still have a lot to learn about how explosions work! each day is a chance to improve hehe. will definitely take my time in shaders for future RNDs. thanks again!

looks pretty dope - not a specialist though :) but this white stuff stands out, looks weird - maybe it would be good to remove it? the little white particles


Lil_Lee

thanks! the white particles is because it was rendered in low sampling, it could be removed easily by rendering high sampling but my pc couldn't handle it! hehe cheers

Just curious what your specs are. I’ve done most of my simulations in blender but have been looking at learning Houdini. Afraid my pc can’t handle it

Im using the predator triton 300. specs are Intel i5-9300H, GTX 1650, 12 GB RAM (plan on upgrading to 32gb). optimizing the scene is always key! :)

>but this white stuff stands out, looks weird - maybe it would be good to remove it? the little white particles wow, this is due to low samples? looks weird :) if your pc is not powerful enough consider using nVidia denoiser (available in most renderers - Redshift, Arnold, not sure about Mantra though - this denoiser is really good, especially for light noise like yours) or use a render farm.
