Main Features of Paint in 3D Unity
Paint in 3D Unity has many features that make it a powerful and easy-to-use tool for painting textures on your meshes. Here are some of the main features:
Full Material Support
Paint in 3D Unity supports all render pipelines (Standard, URP, HDRP) and allows you to paint any texture applied to your mesh (as long as its read/writable), including albedo, normal, illumination, and other textures. You can also write your own texture blending shaders if you want more customization options.
Sculpt, Paint and Blend Meshes
Paint in 3D Unity enables you to sculpt complex shapes directly in the Editor and use the Push/Pull tool to move vertices in positive and negative directions along an axis. You can also paint textures and colors on your meshes with a brush or a paint bucket. You can blend textures and colors using different modes, such as additive, subtractive, multiply, overlay, etc.
Decal and Collision Painting
Paint in 3D Unity allows you to paint decals on your meshes using predefined or custom textures. You can adjust the size, rotation, color, opacity, hardness, shape, and angle of the decals. You can also paint based on collisions with other objects or raycasts from the camera or mouse position.
Mirrored and Fading Paint
Paint in 3D Unity lets you paint symmetrically on both sides of your mesh using the mirrored painting feature. You can also make your paint gradually fade over time using the fading paint feature. You can set the duration and curve of the fading effect.
Paint Counting and Modifiers
Paint in 3D Unity enables you to count how many pixels or triangles have been painted on your mesh using the paint counting feature. You can use this to measure the amount of paint used or to trigger events based on the paint amount. You can also apply modifiers to your paint, such as noise, blur, sharpen, invert, etc.
VR Support
Paint in 3D Unity supports VR devices, such as Oculus Rift and HTC Vive. You can use the VR controllers to paint in 3D space and interact with your meshes. You can also use the VR headset to view your models from different angles and perspectives.
