Simple Renderings Thread

comments and tips regarding adding more realism to the picture are highly appreciated.

with bits of anti-grav tech, as i can see))

That's actually a bug in my scene that makes objects levitate

<3 MLT noise

Displacement works again, then?

That's a lot of MLT samples/second! Has it been that fast or have you done another one of your magic speedups?

Weird results during precedence test

Precedence
glass 3
ice 2
water 1

and the ice likes to get dark when imersed in water :S

[CTZn]

The image tagged MLT is in fact MLT+BiDir

Can you please state the Indigo version pixie ? Using 2.4.6 I've got different results than yours after redoing the scene with Maya... I don't have 2.4.7 though.

In my scene the container is about 1m wide, water has a precedence of 2, plexi and ice a precedence of 3.

Edit: but yeah I've got a very dark ice cube with glossy transparent too, it gets better if replaced by a specular material (MLT 2.4.4). With glossy used, results have a different response with varying pov. That said the ice cube below IS glossy transparent.

It is 2.4.7 indeed, pt gives a quite different result...

My first sci fi project with indigo.


Gee, I wonder why it never occured to me that using textures looks so much better than a simple diffuse texture.

Yes it would be nice if that bug was addressed...



I re-rendered my this old scene. The scale in the old image was off so that the diamond was ~10cm in height

This one uses a correct (or at least more realistic) scale.

there's an outstanding bug with bidir that gives dark edges on some glass.

I just tried a "glass version" of a CAD model...
MLT, once with & without BiDir. With BiDir renders fast as hell, but the result... well...
If you need the scene for debugging, just tell!

Hi Zom-b,
Just working on this issue now. I think I have an idea what it is, so hopefully I'll have a fix soon.

i tried to recreate that beautiful lightwall from Tron: Legacy, but there's a kinda bug or... well, that jagged thing that results from gradient texture. i didn't plan it.

there was another kink with that gradient in "Emission" tab: that wall had 10 height segments, and the gradient was "tiled" on it (instead of being stretched from top to bottom). projection type - UVW mapping.
i "solved" that problem by reducing the count of height segments to 1, but that's not a good solution (i also lost some control of that wall's curviness).

is there something specific that i should know about gradient textures in Indigo?)

[zeitmeister]

Hm,

what host 3d application do you use?
Did you try a 16bit gradient texture?

[jarmenkell]

Cinema 4D

i'll give it a try, thnx

any ideas about that tiling problem?

[dcm]

I posted this problem with gradients month ago, u need to make 32bit gradient in PS to reduce that bugs
