The Paint Between demo scene shows you how to use it, and you can apply the same approach to your VR tool. To paint in VR, you can use the P3dHitBetween component, which allows you to paint between two Transform points. For example the P3dHitScreen component uses mouse and touch data to paint, so it will not work in VR. Most of the example components and scenes that come with Paint in 3D are designed for mouse/touch inputs. VRTK), integrating them yourself should be easy enough, as the components are designed to work using any system that support inspector events, and thus they shouldn't require any code changes. While these demo scenes don't have integrations for third party VR systems (e.g. Yes, this asset has been developed and tested in VR, and supports both multi-pass & single-pass rendering modes.ĭemo scenes like VR HVLP and VR Pen show you how to implement painting using Unity's XR system. Paint in 3D doesn't know how your shader is modifying this data, so any modifications the shader performs will result in a discrepancy between where the texture is painted, and where it actually maps to when rendered with your custom shader.
The reason for these requirements is that Paint in 3D applies paint to your mesh using the mesh position and UV data. If you want to paint these kinds of shaders/materials and notice this offset, then I recommend adding some kind of effect to your object when it gets painted to disguise the offset (e.g. Minor modifications would include parallax mapping shaders, tessellated displacement, heat distortion, etc. Keep in mind that shaders that perform minor modifications to the position or UV data will still work, but the paint may appear slightly offset (depending on the magnitude of modification performed). no tiling or offset).ģ - The mesh positions shouldn't be modified in any significant way. uv, uv2, texcoord, texcoord2).Ģ - The mesh UV data shouldn't be modified in any significant way (e.g. Yes, Paint in 3D is compatible with almost all custom shaders/materials.ġ - The texture you want to paint must be sampled in your shader using the mesh UV data (e.g.
