Hello. I'm having trouble setting the correct color in opacity map in order to make items either transparent or semi transparent. I was trying to create some lace but the color I put in the map is either too dark or too light. I'm using Gimp to create the map. Does anyone have any suggestions? I would like to save a file on my computer so that I don't need to find the correct shading for what I need. If anyone can tell me what color they use or attach an image, that would be great. Thank you.

Using black will make the texture completely transparent and white will make the texture opaque. So pick a shade of gray till you get the amount of transparency you want.

Personally, I keep a collection of solid color 128x128 images to use for this exact reason as well as for placeholder textures when I need to test a mesh.

I'm assuming you know that transparency is achieved with varying shades of gray. The only way I've found to be able to get just the right amount of transparency you want is by trial and error. I usually start with this file which trial and error has shown me to be about 50% transparency:



This is my test image with complete transparency (black) and 50% (gray)



and work from there. Changing the color of your OPAC to either a darker or lighter gray will increase or decrease transparency. Black is invisible or completely transparent, white is opaque or no transparency. Once you upload that texture into the OPAC slot next to the texture, apply your changes and the first texture will go transparent. By applying the gray shades to different areas of your OPAC you can make some areas transparent and others not or less see thru like stockings which are often less transparent at the top of the thigh than they are down the rest of the leg and the toe and heel area can then be made less transparent again.

Checking the blending box can make the effect smoother, but it can also cause clothing items to disappear when viewed thru other transparent items like windows or water in rooms so only check blending on if you really need it.

Hope this helps.

I decided to create some opacities for you to use. So I sat down and started writing a very basic program to quickly generate a handful of them for me to zip up for you but I ended up getting carried away and ended up creating a brand new program for the family, lol.

@soulljah thank you for the info and for the images. Yes, I do know about the black and white alphas but my issue was with getting the correct grey.

@Data when it comes to making stuff, when do u not get carried away? Ty for going through all the trouble. It made me smile when I saw your post.

You're very welcome

Awesome job dude!

With the help of some designer programs you can get opaque textures of some products.
And you can do better shading by seeing it like this.
I would recommend you to find sample tissues first.
have a nice day...
