Hello ppl

I alreade have posted my problem once but nobody helped me myabe that's because I didn't add any illustrations :]  
thing that I do:  
1. convert hdr file to map file using hdrtoxsi.exe  
2. get a sphere with spherical texture projection  
3. connect map file like in that render tree screenshot  
 ![](http://3d.impro.lt/barra/render_tree.gif)

How I should map that texture on the sphere without having those black spots?

Have you tried painting it out?  
I don't know how, but I'm sure it must be possible to bring it into Photoshop and paint out the black spots.  
Check out Paul Debevec's site( [http://www.debevec.org/](http://www.debevec.org/) ) . He probably has some info on that.

P.s.What did you read, to learn about the creation of HDR images? I'm looking for a conprehensible how-to.

HDRShop would be a good place to start. [http://www.debevec.org/HDRShop/](http://www.debevec.org/HDRShop/)

Ok , then you need the hdrshop . I think there is a link on paul devebecs site. it's a cool little program, which helps you to stretch out your hdr image so you can wrap it spherical around yor scene. I think also it's free for personal testing.

hello

I have been trying to make HDRI in XSI but without success ![](http://64.32.63.100/forums/icons/frown.gif)  
i dont get those reflections that you have on your pictures ![](http://64.32.63.100/forums/icons/frown.gif)  
I was just wondering if you could send me the source file for this scene? it would help me a lot.

in shader section of this site, you need a ball projection and not a sphere one
