material maps???

[mcb-sketch]

Do you see any diffarence??? I choose diffuse material; in the first picture only use diffuse; second one diffuse+bump and the last one diffuse+bump+normal...

I am trying octane and I am a student landscape architecture... Can somebody help meee???? or somebody tell me??? (please)

Thank you for your helps...

To be honest I dont see any diference. Maybe you are doing something wrong? Allthough it's quite straightforward.
Have you tried playing with the sunlight (rotate)?

What light source do you use? Cause you can't see a lot of Bump when you use a single color for the whole "sky".

In case you didn't change the environment, try some HDRs or use sunlight.

besides what they have allready told you, the last test is just a diffuse+normal map, Octane when both bump and normal maps are present uses normal and ignores bump map.

[sam75]

use a hdri you will see the difference

[radiance]

use a hdri you will see the difference

or sunlight, that will be the best way to see it.
uniform lighting of a texture environment can't produce any highlights so you won't notice the bump map.

First of all; when I see your replay; I am very happy.
THANK YOU nuverian, prooq, kubo, sam75, radiance thank you so much.
and I am sorry; I think my english isnt good enough. İt can be some mistakes the things which I write...

NOW;



all images has diffuse and normal map...

First one; *select diffuse material
*mesh preview environment is texture environment
Second one; -select diffuse matrial
-mesh preview environment is sunlight
Third one; *select glossy material
*specular set = 0
*mesh preview environment is sunlight
you can see the difference third image; normal map is much more prominent(clear)...

first question; is the prominent(clear) of normal map come from the difference of diffuse material and glossy material??? I think this but I wanna ask the professionals...

second question; Can I take same prominent of normal map when I choose diffuse material type???

Thank you for your answers and patience
Cheers...

Hi!
a lot of talking about bump maps in diffuse/glossy has been done here: http://www.refractivesoftware.com/forum ... f=9&t=2331
and I think some news are coming in the next beta.

cheers,

EDIT: sorry, I just realized you can't read that thread since it's in the customer's forum section... maybe some forum admin can help here?

I just stated that there is currently no power control for them higher than 1.0 as it's a texture channel and textures are always in the range 0.0 to 1.0
I'm adding a power value in 2.3 to give it more effect.

Also, people who import very large models by accident due to wrong scale can't get enough 'bump' as the power basically dissapears the larger the model, and you can't go above 1.0.

On the other hand, using an uniform environment and a diffuse material does'nt work well,
you really need a sun lightsource (which is directional).

Normal maps should render perfect though, and they don't need a depth parameter as they are given as is.
If it does'nt look ok with a normal map then the normal map used is of the wrong type.
