View Full Version : Mental Lighting and modeling for 3D building

Hi everyone, I am new to CGtalk. I found the site last year and insteadly fail, in love with her. I am in Architecture practise and now into 3D model with 3DMAX.

The problem with the modelling is that I started with AutoCAD and later I exported it into MAX for lighting and rendering. as you can noticed, on the left, some part of the wall surface is inside out, or even gone. to use the normal and unify -> face is time consuming, any suggestion for faster solution.

I used Mental Light in this case to render and I found that the Glass is not transparent even though in Material Editor I set the opacity to 50. when I used scanline rendering, it is normal. anyone out there can help me to improve the modeling and lighting?

Thanks for viewing.

I have found that welding vertices is the cause of such artifacts. adjust welding vertices parameters , or ( as i do ) do not weld vertices when importing your modle.

are you going scanline or Mental Ray rendering?

Hi, Thanks Saeed-E for the tips, really useful. Right now I just process to experiment more lighting effect, this one was rendered by scanline, as mental light tend to bounce light too much until the glass lost its transparency. (am I correct????) and I am abit frustrated with Caustic generated for reflection and I came to a conclusion that Mental light is not suit for this case?
The lighting for this one is from below and more spot lights from below to create evening or night scene. Later I ll try to compose with backdrop and environmental elements.
Thanks !! :)

It's not that its not suitable for this type of work, its moreso that the techniques will take you a while to learn properly. It's easy to dismiss it at first, but give it some more time and plenty of learning / practice and you'll get there. For an easier alternative, and some say faster for architectural work, Vray renderer has some great features.
