Prepare Hairalpha in PSD to 3dsmax Settings

Farina

Hello again!

I want to make hair, so i did these steps (please correct it)

1.) Search for hair on google (but which size? )

2.) take it to Photoshop. (here i dont know, how big the document should be)

3.) draw the alpha out of the hairreference

4.) Save the diffuse and the Alphahair with TGA 32BIT, because i want to have loseless maps

5.) Take it to 3dsmax and draw a plane.

6.) Put the Diffusehair and the Alphahair to the materialeditor (opacity)

7.) I have my hear on the plane.

My question is.. im not really sure, which sizes i should use, which document size in Photosop, how many pixels? How big should be the widht and lenght of the plane in 3dsmax, where i put the hair on?

I want to have the hair loseless at the end.

Somebody could help me?

Not sure if these are on the wiki. The first three are general overviews that may answer some of OP's questions. The last one is a nut's and bolt's of the xgen method some of the others refer to :

not sure any of these are going to discuss what size textures to use for your hair. My answer would be, as big as possible if it's portfolio work. If its for a game, as big as possible until there is a need to downsize. so 4k. Downsizing it no issue.

Hair planes will just be sized in relation to the head they'll go on.

in addition to the wiki here, 80lvl,  marmoset, and lesterbanks are great places to browse for boatloads of info.
