Chaos Corona for 3ds Max => [Max] I need help! => Topic started by: fa2020 on 2016-10-27, 22:43:52

Hi guys,
I'm gonna model a penicillin vial and the powder inside it. I don't have any idea how to make its powder to get a photo-realistic image. I provided you a real vial model. As you see in the photo, the powder has been scattered randomly over glass's wall. Please guide me to model the powder like the photo you saw. I use 3DS MAX and Corona.

what about to duplicate the model, to delete all outside faces, to scale it to 99.9% and use the the map for masking? refract IOR=1. Or just opacity mask.

In photoshop generate some clouds. Up the contrast with levels.
The more white areas the more lumps of powder you will have.
Add a gradient ontop to create the 'full' part of the bottle.
Depending on how defined you want the edges you can apply gaussian blur.
Create a second glass material, set the diffuse to white/whatever colour your powder is and plug the map you created into the refraction colour slot.
Duplicate the inside faces of your bottle and scale them to 0.99 as mentioned above.
Apply the masked glass material to the inside faces and the normal glass to everything else.
Ive attached the map i made for reference and a render to show what it does.
Good luck!

here idea with procedural maps

Yeah you can achieve the same effect as the map i posted with a noise map, a ramp and a composite map too :)

I think it'd be better to plug it into opacity. Right?
