Texturing organics: material tests

Hi friends,

With all those new Sketchup plugins to do organic modeling, I though it would be a good exercise to try to materialise these forms.

So here some quick material tests.
The textures were projected to the the surface.
- Machine: octocore MacPro running Vista 64bit
- Render time: between 3 to 6 minutes for the SSS and glass renders.
the displacement renders took 8 to 13 minutes.
- Original image size for all images: 1230 X 835.
- Lighting: pure physical sky.
- settings: Irrmap+LC

Skin SSS:

Glass no caustics:

orange car light + caustics:

Glass + caustics:

Stone + displacement + soft shadows:

Another stone + displacement + soft shadows:

Grass displacement + soft shadow:

Thanks for watching,

Biebel

Re: Texturing organics: material tests

Since this is a “lab” post, d you care share this model? (with the vismats). I wanna make some HDRI tests but i can´t handle displacement.

Cheers! 8)

Re: Texturing organics: material tests

very nice biebel, the stone ones are a beauty, congrats, btw, i once try to apply a displacement on a bark texture on a high polygon tree, but when i render it the part of the tree where i apply the texture was gone, dont know why..but congrats to you bro.

Re: Texturing organics: material tests

very nice.im not good at displacement.The stones looks real man…well done.

Re: Texturing organics: material tests

Thank you Kgoku, Teofas and Mohd-akmali.

@Kgoku:I’ll try to upload the SU model tomorrow on 3Dwarehouse and post the link here.

@Teofas: Maybe you experienced a RAM issue because of a high resolution displacement texture you used or maybe too high displacement settings?
I learned in this experiment that testing using really low .visopt file settings, the RAM is controlled much better (I always check the task manager to see how much RAM is still free while rendering).

Here’s that stone render at original size (saved for web to lower file size):

Re: Texturing organics: material tests

wow, i love those glasses with caustic. very good indeed. also those displacement materials rocks. ;D

Re: Texturing organics: material tests

Thanks Nomer.:slight_smile:

Re: Texturing organics: material tests

Yeha i realy like it, could you make a favor for all us??? Explaing how did u mapped the texture??? Please is very good.

Re: Texturing organics: material tests

how thit u texture it?? using projetion in sketchup..? it looks realy nice

Re: Texturing organics: material tests

Yep - superb displacement examples. For us displacement newbies, maybe you can explain a little more about settings etc.. I particularly like the rocks.

Thank you guys :slight_smile:

I didn’t change the default global displacement values. Instead I tried to define the strenght by playing with the multiplier in the displacement slot of the material.

I used the standard ‘projected textures’ method = pipeting the texture (which I right clicked and set to ‘projected’) of a face and paint bucket it to the whole surface.

Some more displacement, both on the object as to the ground surface:

Re: Texturing organics: material tests

Do you make a disp. map in Photoshop to create the stones..? becoulse when I try it I get al kindes of sharp eddege in my render from the disp. map. :frowning:

Re: Texturing organics: material tests

this is what I get :frowning:


Re: Texturing organics: material tests

hi bibel
excelent as always!!! but its does seem to good to be true, that mapping seems impossible with those new UV mspping tools and with projection… your gonna have to give us meatheads a demonstration or tut!!!

could i see i hidden line screen shot?

Re: Texturing organics: material tests

our parabens ;D.. very perfect .. the stone was very real
hugging .. ;D

Re: Texturing organics: material tests

Thank you all for the comments:

Non-believer! ::slight_smile: ;D

It’s really the common ‘texture projecting’ method…but since you ask for it here’s the tut.

I used a premade displacement map but it can be done in Photoshop as well.
Unike a bump map, you don’t want too much detail in the stone itself
. Only the parts that really need to be displaced (=the seams between the rocks). The rock itself should be mono color grey or white.

You need to take good care of the edges on that seam. It helps to use ‘gaussian blur’ just a little to get it smooth. Also using levels (bring black and white closer to the curve), the ‘photocopy’ effect and also the ‘treshold’ option (image menu>adjustment>treshold) can be handy to use.

And a last material experiment using displacement:

Re: Texturing organics: material tests

very nice tutorial, actually i was looking for some info like this thx.

Re: Texturing organics: material tests

So when you are using the stone texture you aply the disp. map to the sketchup moddel and than link it.. and aply the diffuse map?

Re: Texturing organics: material tests

Get out of here! :slight_smile: We struggle for a decent carpet displacement, and you came with this… are you a wizard or what???
