There are plenty of textures in my library, but how do I create my own? What program do I use and how do i make them?

You can create textures in a photo editing program like photoshop or Gimp. Gimp is free to download and use.

I think Axeman made a tutorial on how to do this in photoshop. I looked but couldn't find it. It's floating around somewhere.

Anyway... you can use a photo for reference or draw/paint your own but I beleive it has to be greyscale... black and white.

I haven't seen one for Gimp but I can make a video tutorial for you if you want. Just let me know what kind of texture you're looking to create. Cool?

So I ran into some issues.
I can open the images as textures in Visionlab but...
A. They either come out black or...
B. They come out looking a bright chroma green.

I'm not sure why this is happening but I'm essentially following the steps in the link below provided by Axeman for a Photoshop tutorial... I"m using Gimp though.

I followed those instructions but when i opened vision lab studio it didn't want to open the new texture. I wanted to make it from this leaf

Could you please make a tutorial showing how to make the texture? It doesn't have to be perfect. Top right leaf.

Hi there. Do you understand alpha textures, and how to create them in whatever program you are using to create the textures? If not, then what we need is a tutorial on using your image editor, not on creating textures, whi9ch involves heading in a bit of a different direction.

Basically, you need to select the leaf, and create an alpha channel which removes everything outside the leaf. the way i typically handle this in Photoshop is to select the leaf and delete everything outside it, leaving the surrounding area transparent. Depending on the software you use, it may work a little differently. Then desaturate the leaf so it is only shades of grey. DON"T convert to greyscale, what you want is an RGB image containing only grey.

Then, adjust the image size so that it is 256x256 or 512x512, with the leaf in the middle, oriented the direction in which you wish it to appear. If you want the leaves in your particle effect to be pointing various directions, you'll need to rotate it and create a separate texture image for each direction the leaf should be in. If you only use one texture, as the image is now, all of the particles will be leaves with their tips pointing directly upward.

Once you have the size and orientation done, and the leaf is greyscale with a transparent background, save it as a .png or other format which supports alpha channels, and you should be good.

Aha! Thanks Axemen, I was converting the image into greyscale rather than just desaturating it, that may be why it was coming out weird when I imported into V.L. as a particle texture... wait... Phoenix Studio Production, you are talking about particle textures right?

Alright! biggrin

I just did a quick test and Axeman was correct about desaturating the image rather than changing the RGB to gray scale. biggrin

I'm working on a commissioned portrait right now for a friend's birthday party tomorrow. I'm almost done with it so I'll start on that tutorial for you as soon as possible.

Hey,
I was gonna keep it short and simple but I decided to do an extra bit on how to achieve a smoother animation. It'll be a little longer to render out and upload but it should be done today.

Na, didn't forget. Trying to lower the file size right now before I render so that it won't take so long to upload.

EDIT.
Here you go. Hope it helps.

That was really good, thank you so much. The leaves look pretty real once graded. Thanks, not i can make new particles and stuff, to add into my new film. I'm not sure if you've heard of a movie called "Push," but I'm making a parody and I'm changing some of the powers around, and entering it at my schools film festival. I'll post a youtube link when it's done. smile But it'll be a while. Like In september. Because I start filming during spring break.
