Title: Rendering for Architecture
Post by: trafalgar on July 29, 2010, 08:45:47 PM
Hello!
There is a lot of exterior escenas (without ceiling, wall) but I can't see interior rendering.
In KeyShot is posible make it (for architecture - Images in night )?

Thanks

I did an interior render with all closed models without deleting parts...just import an object that you will transform into a light material and uncheck visible to eye, reflections etc. The power depends on the size of the object

just a direct import no tweaking of materials yet...

Looks great.
Title: Rendering for Architecture - outer & inside

Thanks by reply:
I followed your recomendations but I have two problem:
1 - In preview rendering  imagen is dark, impossible work inside (as real time).
2 - At final rendering  light vs shadows is not very real.

Yours imagen are very good! but principal lights is a exterior (HDRi). 
A last question: What happen with HDRi like "emissive material", work it or it is the same than  typical material? 

Thanks again

just convert any material into emissive no need for hdri map however you can use texture map to take into account its color...you can play with this to have varying effects...

just uncheck detailed shadows or just hit s to turn off ray tracing and speed up your navigation....check it again after you've applied the materials and established your view. Save every camera view whenever you move because currently there's no undo for the camera...

unchecking detailed shadows works like a decal mode or just a plain shading like in hypermove. It is ideal for heavy scenes or dark areas. Check detailed indirect illumination to let light pass through glass. For the second image I didn't imported a geometry coz i'm just playing with it and it's pain in the ass to manipulate imported goemetries...added gizmo is also helpful but i tried hypermove before and it is so much easier to merge imported objects. There is also no option to duplicate object parts. Anyways, I just converted the window glass into an emissive light. Checked double sided, unchecked visible to eyes and reflection. It works like light portals.

Not really .. it is still fully raytraced, just without shadows. To further enhance performance turn off ground shadows in the environment tab.

yes thanks...it is still raytracing...i thought adding a decal mode is useful but turning off detailed shadows and ground/detailed illumination is enough
