Can't get support in upper part of model

[Pekish79]

vray corona or octane i always like to try all programs

honestly i stick to Vray mostly because i have a large library of object in Vray and I don't feel like to jump to octane or corona

I have to say Corona/Octane have some cool feature pretty impressive the real time render (octane) is great and snow seem to be much easier to model/render

Overall if you are starting now I would probably suggest to try using at least 2 Vray and or Corona or Octane
Vray because is the standard most office use it and you don't want to "not know it"


if you want to see how professional use VRAY you definitely need to check http://www.the-boundary.com/
if you want to see what impressive use of VRAY but recently octane/corona you need to follow this guy http://www.bbb3viz.com/

BTW corona and Octane are VERY user friendly so if you learn VRAY first you will have no problem moving around the other 2

Never tried octane or corona. I've used vray for around 10 years. I was more curious what you use to model with? Rhino, solid works, max, etc?

depend from the type of model i need to do honestly speaking for solid regular geometry like a normal square like building i find it faster to use Autocad
I did use Rhinocheros when the solid must be made of faces and not "full" geometry but lately I never had to go back to it

if i have to do organic shape is impossible with autocad i obviously use 3DSmax but really how often you find a client willing to pay a building where each piece is custom made

In the real world I think autocad is what i use the most for 3d modeling even if the technical drawing plan section elevation we usually do them all in Revit
