Indigo Renderer Forum

My partner's dad painted this still life:

So I decided to model it in blender and give it a try with Indigo. I also wanted to show him Indigo's capabilities to simulate real life lighting and reflections:


update: Nov.26/06
-added wrinkles on the floor
-added DOF
-added bumps (dents) on the jug

update: Nov.27/06
-lowered apple's material reflection
-closed the apple's stem circle

Any C&C is welcome

Nice pic. You'll want to take the exponent value right up for the nk file though

Try and make the apples more irregular, make the bit where the apple stem (right word?) comes out deeper. Also sort out the seam!

Look forward to updates!

Thanks Ian. How do you change the exponent value in the NK file? I checked it but all that was there was a bunch of coded numbers; no exponent values to change
Right about the apples and the seam. Working on them, Already started working on the jar's "mouth" and kinda sorted it out but now It looks as if I grabbed a hammer and hit ti bad with it The jar in the painting indeed has some bumps but mine crossed the line; also proportions got bad and lost the nice base I had in the first version. I overdivided the lattice Going back to a previous stage and checking those apples.

The exponent must be changed in the xml. When you export do "separate materials" to make finding it easier

Just change <exponent>50</exponent> (or whatever number) to <exponent>100000</exponent> (10,000 plus really)

Hi Afecelis, this gone be a nice render!
good luck

this is gonna be awesome! cant wait!

Thanks guys for the comments and suggestions. Quick update.
1. Finished modeling the jar.
2. Moved the apple's "belly button" towards in.
3. Checked apple's texturing.
4. Changed lighting from exr to a mesh emitter to make it more similar to the painting.
5. Raised the exponent in the nk material to make it reflective.

Now the problem is that the silver material is only reflective in front of the camera. The sides of the jar are showing up black. Any ideas?

here's the new shot

Very nice afecelis.!!!

Hm.. the metal seems really strange.. maybe the fresnel factor ??

cheers

thanks U3dreal!
well I made some tests. I applied several nk metals to it (Cr, Au, Al, etc) and the result was always the same, but then I rotated the model 90 degrees and....

So it must be a normals problem Unfortunately, the normals seem to be ok in blender, so I'll probably have to re-model the jar from scratch.

ps. As usual, I also tried the scene in kt and things were a bit more complicated there, specially with the metal materials

Yeah that's a pain, I can never really tell if I need to flip the normals.

Is there going to be any hdri mapping of the jug?

jug! that's the word! thanks!

First image had hdri (exr) lighting. I'll retake it once I fix the....JUG, hehhehe

ahhhhh!!! nailed it! Remodeled the jug and got the trick to work!

wire view:

quick render:


now I can work on improving the other materials and trying out the hdri version again

Just a heads up, if you don't enclose the scene in a box, it will clear the noise earlier (rays end up bouncing around until their max, rather than a few times and out)

wow, looking very nice! thatill be a keeper!

you're absolutely right! It also helps enhance the reflection effect on the jug. New version:(updated above)
