displacement issues

[West1000]

Hey guys. Hope I’m not crowding up the message board. I have been having displacement problems…..actually I’ve never been able to get it to work. I was able to get the bump maps to work but displacement doesn’t seem to want to work. I have been doing it the same way I do the bump except I check the displacement box. I make sure to use a bitmap in the diffuse and a greyscale (bitmap) in the displacement part. Is there something I’m missing? When I click update…I can see the displacement happing in the little update view thing….but when I render….nothing happens. It’s driving me a little nuts…lol. Thanks again for your help. ;D

PS I have been going back to look at previous post, but no luck

oh...I have read the manual many times.

Re: displacement issues

try changing the multiplier to something higher and also make sure the scaling of the bitmap isn't too small. also its not necessary to use a gray scale image. displacement just takes dark values out of the picture. let us know how it goes...

Re: displacement issues

Are you saying that I should use the same bitmap image that I used in the diffuse in the displacement?

Re: displacement issues

Can you tell me how to attach an image in my message so I can show you what I'm doing? When I click the "Insert image" button...it puts some kind of html code on my screen. I'm use to "attach" like in hotmail.

Re: displacement issues

yes i usually just use the same image for diffuse and displacement. to upload an image upload it first to photobucket.com and copy the code that has the "[IMG]" in front of it to your post here.

The second photo is my difuse map.
The third photo is my displacement map. I tried jacking up the multiplier to 4 but still no luck.


I have another question. Arroway provides users with all the appropriate maps to make their textures. I noticed they provide us with a reflectivitly map. Would I place this image in the reflection layer or would I insert this in the reflection spot located next to the bump and displacement boxes?

Re: displacement issues

Is there any other setting that I am missing? Is there anything I'm suppose to do in the main settings tab? I can't remember the name of that tab...it has an enviroment roll out...etc...) I'm at work and I don't have the software on my computer to check the name.

Re: displacement issues

I figured it out!! ;D I didn't group the object that I was applying the displacement texture to. I was applying the texture to a surface. You have no idea how long this has been driving me nuts. lol

Re: displacement issues

doesn't it feel good when you finally get it right after a couple weeks of no luck =)
