Indigo Renderer Forum

hay im currently playing about with indigo for architectural visulisation ideas and came across problems with blacked out / opaque windows on exterior scenes... even if i use an exit portal.. found some solutions on this here fab forum [actual lifesaver] but they all mention bidirectional paths and i cant find anything that tells me what it is! sorry complete noob question but loving indigo because its a renderer i can actually use ^.^

oh im using it with skindigo! didnt know if thats relevent

if some one could help that would be fab!

Make sure your windows have a thickness! Try changing your tonemapping to Camera and playing around with the values and try turning bidir and MLT on and off.

thanks for the reply! by my windows having a thickness do you mean them not just being a single face?

Yep.
Window and generally glasses have to be thick to be rendered properly.

If you want to speed up the calculation, you may want to model single-sheet glass for the windows and apply the Thin Glass shader. No caustics but faster rendering.

works perfectly. thanks very much!

sorry!! another probably really obvious question! thought id put it in here instead of annoying people with a new thread when i try to put a displacement map onto a wood texture this happens.. (see image) does this mean i dont have a displacement map? and if so how do i create one?

The faces are displaced, so obviously you do have a displacement map.

The problem you're having is that the faces of your cube are not connected to each other. That causes indigo to displace each face individually instead of doing it nicely around the corners. Also you should check the offset value of your material, it should be 0 in normal cases. And scale is also important, the displacement seems to be quite heavy for simple wood material.

hi! i have set the scale of displacement to a little bigger than needed just so it was clear on the screenshot what was happening.. you couldnt see it that well before.. but whats an offset value? is it something altered in sketchup or skindigo? and how would i go about joining the faces together???
sorry!

I don't know about Sketchup, I'm a Blender user myself.

Offset value is a constant value of displacement for Indigo materials. So it's altered either in the exporters (skindigo) material editor or in Indigo material editor.

Actually the C parameter can be negative, this would push the faces back, in the opposed direction of their normals.

The way to get faces stitched is a bit counter-intuitive: edges to be welded have to be smooth, or they'll be separated by all means. So, smooth all edges to be welded, enable subdivivisions but not shape smoothing so to keep the result within the desired aspect.

Sorry for I don't know the very SkIndigo terms to put this

Rounding the edges on your model should do the trick. Try this: http://forums.sketchucation.com/viewtop ... 23&t=20485

Must have blender equivalent of this script

@CTZn - it okay! ive smoothed the edges in sketchup and that seems to have worked.. thanks! but whats a C Perameter?

@Stinkie - thanks for the link! ive been needing something like this for ages!

thanks for all your help guys!

@ Borg: Why? Doesn't Blender have a bevelling tool?

@ Rhibee: You're welcome, obviously.

whats a C Perameter?

It's also called offset, as mentionned by Silmä. Sorry for I'm sticking with technical definitions

Glad that worked for you !
