View Full Version : Displacement Problems

Hi Guys.

I have 2 questions.

1-I sculpt an object but when i extract displacement map, the map is so much lighter than what i sculpted. Look at my example below. Even though i sculpted very deep holes, the map looks gray and no black spots at all.

2- I want my box's edges to look like this(the image below). I create a simple box in 3ds Max. Then i send it to Mudbox. And sculpt it like in the photo and i extract a displacement map. But when i render it it doesn't look any good. What is the solution to make edges like this? I need a real help about that or i will lose my mind.

Note: If you know any tutorials teaching the sculpting and extracting displacement maps and using it in 3ds Max, please share that with me(doesn't matter free or not)

you could test the dispmap... if the displaced object looks like the original everything is fine...

import your level0 into a new mudbox scene...
subdivide it up to the same polycount as your highress was...
displace the object with your dispmap... maps --> sculpt using map

to get good looking displacement its best to have an even distributed quad mesh as base...

Dear oglu. Thank you so much. This tutorial you gave me worked very well.

I have 1 more question though.

I do environment art works. I don't create games or stuff like this. I just create single frame works. Do you think that i need to work with normal maps or displacement maps? What's the difference and which one is the one that i need?

I need some serious help about that. I am so confused.

I will need some more tutorials about workflow between mudbox and 3ds max, extracting maps though.

Thanks so much.

take a look at the tutorial i posted above... thats the trick...
your base mesh needs to be much more even and quad based...

"your base mesh needs to be much more even and quad based..." this is what i need to hear sir. I get it now...

But still some little confusions. What you mean by "even" is that the polygon sizes should be similar. Is that right?

Thank you sir.

right... all edges should have the same length...

Master "oglu". You are a genius. What you told me totally worked for me. But i still have 1 more confusion :) .

For example i have a geometry which isn't "even in terms of polygons". And before i send it to Mudbox i make the geometry "even" . And i sculpt it in Mudbox. But after i extract the map from Mudbox, i can use that map on the first geometry which wasn't "even"(in 3ds Max). I mean to work on Mudbox i need an "even" geometry but i don't have to use the map i extracted on an "even" geometry in 3ds Max. Is that true?

Use the even version cause displacement is working much better with even quad meshes. The trick is to model a even quad mesh but with low polycount. You have to find the balance between working for dispmap and easy to model.
