Hi all
there is some nice work going on here.
i have 3d Studio Max 8 and i have Brazil, i can get the Scenes to work but i need help getting my skins onto the cars? any help would be nice. thank you
How do I add my skin to the car?
--------------------------------
- Press M to bring up the Material Editor.
- From the material list, click on the button marked:
body [ADD SKIN] ( Brazil Basic Mtl )
- Next to the 'Diffuse' colour, click on the small, blank square button.
- Select 'Bitmap' from the list and browse to your skin file.
- Press F10 to bring up the rendering window
- Hit the Render button and make a coffee =)
then it must be your material. normal car glass isnt very thick so the best refraction is set at 1.01 or 1.02
however.. motorcycles have thick glass (well.. plastic) so its up at like 1.5 or so
IOR isn't matter of the thickness.. glass material usually has ~1.5-1.6 IOR. and becouse all objects have two surfaces light travels through the AIR/GLASS and then again through GLASS/AIR surface so it's not becouse IOR either
(RAYs bend 2 times so bending is +/- 0)
And yes my object has thickness (~4mm) so it behaves like real glass. IOR is 1.6
try lowering and just do some test renders of the lights themselves to save the time, because it may be that your IOR is .. to high.. 1.6 is very high imo.. for something not that thick
there shouldnt really be much (if any) refraction the headlights since they are so thin
did a little research, and glass is ~1.5 IOR.. BUT.. refraction increases as the angle increases.. for your shot.. there is very little angle front being strait with it.. it shouldnt be bubbly like that
I'm not a professional modeller, but Sniiki is right. Glass has an IOR of 1.5/1.6 no matter how thick it is. IOR depends on the actual material, not the dimenions of the object.
If the glass is thin then the light wont bend much because the light exits almost as soon as it enters the glass.
about 1/4 the way down theres a little tool you can use, and its showing what im trying to say
your car is near parallel with the camera.. yet there is an awful lot of refraction, that should not be so.. now if the camera was perpendicular to the car.. then it would look okay.. but still akward, i've never seen headlights bend light.. that much
no permission blah blah blah.. that happens everytime someone tries to show us a screenshot of it from there.. why cant whoever runs that website turn that thing off.. what are we gonna do with a picture.. really?
Thanks to Ian.H at dS Autos for the scene. Apologies for the size - limited by the free 'learning edition' of Brazil Rio. Now the learning needs to begin!!!
Made a copy of the object on which the drops will come, then gave that copy a water material. Then with vray's displacement mod made the drops, using bump map (made in photoshop). Remember to use "water level" setting in displacement.
