lighting fluids in a bottle

cpz — Mon, 02 Apr 2018 19:50:36 GMT

Hi, I am having a lot of trouble, lighting a beer bottle with beer in it. Does anyone have a good solution, ie, lighting setup, placement, etc, I'd greatly appreciate it, thank you . PS-I am in C4D, My rays are high, about 12, and I am still getting some "black" in my glass, thank you

Can you share some screenshots about it?

Thank you for your reply- my beer bottle is large, tried to get it close to size of the larger bottle, which looks fine, but I am at wits end ;( screen-shot-2018-04-02-at-40533-pm.png

BTW, here are my settings, maybe the model has problems,? screen-shot-2018-04-02-at-40955-pm.png

Can you upload a simplified scene file? Looks weird, the problem can be different things

Your settings looks fine, maybe the model have the internal normal direction wrong, it's the same material that you have in other models?

trying to reduce file size, if I can not get it small enough, do I have other options?

I took a lathe model, and made it editable, that is all that I did

Hi, I can't seem to get my folder smaller than 2.1 I'll send w/o backdrop, ok?

Sure no problem

BTW, I didn't make the lathe editable, it may make the file size too large

You only need to reverse the normals from the geometry :).

thank you, I'm confused, I made a lathe/spline, made it editable, I don't know where I went wrong,? also, if I put "beer in my bottle", I should be able to see transparent bottle with beer?

Sometimes some creators objects from c4d make objects with inverted normals, you can flip the normals here without make them editable:

Yes but if you will make the bottle with Lathe too, you will need to make a thickness profile, like this:

thank you for the revelation, about the "flip normal ", forgot about that- I do know about the thickness. I REALLY appreciate that you went above and beyond here, much obliged, best, CZ

BTW, one more question, if I may, I'd like to have my beer color, similar to a Corona, but even if my depth is .o1, it is still to saturated, I've tried to make my model larger, but I still get overly saturated tints in my "beer/fluid", any thoughts,?

I saw in your material that you have activated a little bit of diffuse and I don't remember what other channel but you should be try to recreate the beer material only with transmission without diffuse. And the lighting it's really important to define which look that you want to get.

I don't know exactly which amount of depth you will need for a beer but if you want to make a calm beer maybe you don't need a scattered transmission.

ok, I'll leave scatter alone, thx !
