General issues

The provided scenes do not work

If the provided scenes do not work, your hardware/software setup might not be supported. First, verify that your operating system is Windows and that your computer has a CUDA-capable NVIDIA graphics card.

I cannot run a standalone application

Make sure to enabled Allow CPU access on the meshes you are using by double-clicking the mesh asset and navigate to General Settings:

I experience unexpected crashes

The plugin is in a quite early stage, so there might be unexpected crashes. If one does occur, please locate the [ProjectName].log file and send it to us, explaining what steps you did before the crash.

Runtime issues

The simulated objects are static when I press play

Make sure that your scene contains a Deform Manager and that the objects that you want to simulate contain a Deform Body Component.

My simulated objects get a force that they shouldn't

First, make sure that the gravity and wind forces in the Deform Manager are correct. If the problem persists, try disabling the self collisions in the Deform Manager. If this solves the issue, but you still want self collisions, you might have to modify the mesh you are trying to simulate to contain more uniform triangles or tetrahedra, alternatively enabling Remove Intersecting Particles or Enable Surface Sampling inside the Deform Body.

My simulated object is falling apart when simulating

Make sure that your mesh is correctly connected by edges and triangles. If there are disconnected parts of the mesh, it will not create constraints between these parts. Try to make sure that the mesh is not using flat shading, that might sometimes split vertices in the Unreal importer.

My simulated object is very stretched and slow

Please make sure your imported mesh doesn't have flat shading enabled. This will make Unreal Engine generate extra vertices. You can also try to change the import settings of the mesh by double-clicking the mesh asset and navigate to Import Settings. There you can try to set the Normal Import Method to Compute Normals and Normal Generation Method to Built In.

I cannot interact with the cloth

Currently, you need an orbital pawn in order to interact with the cloth. The orbital camera can be found in DeformPlugin C++ Classes > Deform Plugin > Public > OrbitalPawn. The Orbital Pawn uses the projects input mappings. You can load those input mappings by following the steps in Installation. If you want your own way of interacting with the cloth, you can look at the source code of Orbital Pawn.

The cloth is blurry

This sometimes happens when using temporal anti-aliasing. We recommend that you switch to another type of anti-aliasing in the project settings when using the plugin. We are working on solving this issue

Editor issues

The paintable vertices do not show up

Make sure the object you have selected is compatible with the type of property you want to paint.

I cannot paint the vertices

Currently, the way to paint the vertices is by holding the left CTRL key while moving the mouse over the vertices. This will be improved upon in future updates. Also, make sure you have the correct coefficient value. By default, these values are 0, which means that the paint will be white.
