Editing Textures on a 3D Model in Procreate

By Occuria

• Extract mesh files and convert from FBX to OBJ
• Import your mesh files into Procreate by drag and dropping or selecting it upon prompt
• On the right side layers menu, select the mesh piece you wish to apply your texture to
• In the drop down of said layer named "Base Layer", select the little 3D cube
• Select the "Color" box
• In the top left menu, select the little wrench icon
• Select the "3D" cube tab if not already selected
• Turn on "Show 2D Texture", the page will turn blank
• Select the "+Add" tab
• Select "Insert a Photo/File"
• Choose your texture, let it import
• It is now applied!
• Repeat these steps to add your Normal and Metallic maps
• Turn off "Show 2D Texture" to view it on the 3D model.

You can draw directly onto the 2D texture or the 3D model itself. Drawing on the 3D model itself may result in a more distorted image.

DISCLOSURE:

While the texture files themselves (not added to a 3D mesh) will import to Procreate with 4k res, if your iPad is not strong enough to support a huge load, your 3D mesh import will revert to a 2k res size, instead of 4k. So it's best to keep that in mind when making tiny edits or designs.

Editing Textures with Alphas

By Beckaboo

• Gimp: Colors > Decompose > Decompose to RGBA
• Gimp: Colors > Compose to RGB
• Gimp: Export composed image
• Photoshop: Open composed image, make edits
• Photoshop: Export edited image
• Gimp: Open edited image, decompose to RGBA (Colors > Decompose > Decompose to RBGA)
• Gimp: Copy alpha layer from original decompose
• Gimp: Paste into the decomposed RGB at the bottom as a new layer
• Gimp: Recompose the image (Colors > Compose > Compose to RGBA)
• Gimp: Export as .tga OR export as .png, checking the box to "Save values from transparent pixels"

AMMS Masks

AMMS mask channels:

• Red Channel - Ambient Occlusion
• Green Channel - Cavity
• Blue Channel - Metalness
• Alpha Channel - Glossiness

AMBIENT OCCLUSION:

ambient occlusion, in principle, is like bounce light and how much shadow the object creates just by being near things. like how there will be a shadow underneath a car in the bleakest and flattest of cloudy days. there's no directed light casting the shadow, theres just not much room under the car for ambient and bounce light to.....bounce into
