Texture Maps issue, please help!!!

[jsuarez388]

Hi guys,

I am working on a Rock/Moss scene in c4d+octane, and I can't figure this out. I've downloaded an image from cgtextures.com and used CrazyBump to get the texture maps, but even though these are very high res (3000x1933x24), I can't get the detail in there.

Maps

This is how the render is looking

My C4D Setup. Tried subdividing the plane more, but it didn't make a difference.

This is the level of displacement I am trying to achieve. I doubt this guy spends +$80 every single day to buy 8K maps for his daily renders.

Am I missing something here? shouldn't I be getting a photorealistic image? By the way, I saved 32 bitmap images from CrazyBump, but I am getting 24bitmap in C4D, why?

NOTE: I have low samples and diffuse passes because I tried increasing and didn't see a difference.

Hi jsuarez388,
In general, the classic displacement map has the great deformations while the fine details are stored in the normal map.
Octane Displacement is a bit different, it gives the best results if the major deformations and the fine details are stored in the same map.
CrazyBump with default settings works in the classic way and tends to blur the displacement. Here is a fast example with a generic 2k texture converted in CrazyBump:

On the right the classic CrazyBump output, on the left the displacement is obtained by converting the CrazyBump Normal map into bump with Photoshop. Obviously the more resolution you have, the more you can go near the texture.
If you want to try the power of Octane displacement, try with this free demo textures from real-displacement-textures.com:

Hey @bepeg4d thank you for your help!

So, in conclusion to be able to get a photorealistic displacement like the sample picture that I posted, the only way is to have 8K maps? My map is 3K, and to me that sounds like it should give me very detailed displacements and a good detailed diffuse map, but that's not the case here.

I just want to know if I need to activate something in C4D or Octane to be able to get more data out of the maps and therefore better displacements. I know the maps from this website you suggested are great, but I can't spend that ammount of money to buy them, that's why I have an account in cgtextures and spend some money to be able to buy a bunch of high res textures.

Any other program you can recommend to create texture maps from a photo?

I am using Bitmap2Material from Allegorithmic and it works fine.

Great, downloading now to try it. It looks way more professional than CrazyBump. Just curious, what resolution images do you usually use to create PBRs?

I am looking to know if I should get an account in a website like Poliigon where I can download 8k images, or if Cgtextures is fine and download 4K images at the most to create PBRs
