Help needed with Custom Healing Item

[Mudbill]

The problem is that your texture is incorrectly applied, so it appears invisible in the game.

I assume you've edited the .dae file with a text editor to point to a new texture, since this looks like the wine01 model. But it appears you've named your texture wrong, or put the wrong name in the .dae, since you have estus01.dds as your texture file, but estusflask.mat as your material in the .dae file, thus it's trying to load estusflask.dds instead, which doesn't exist.

Additionally, the model you've picked, wine01, has 3 textures baked into it (a normal map and specular map). Normally this is handled in the .mat file but looks like they are present in the .dae file this time. But this doesn't seem to be an issue for your model, though it does fetch the original normal and spec maps which will affect the texture of your model.

Anyway, to fix it, rename estus01.dds to estusflask.dds, then load the .dae file using the Model Viewer. That should fix the model.

Now, the entity file is incomplete. You've created a shape but you never made it into a body. You must select it and click "Create Body" in the Shape tab. The entity must have a body if you want to interact with it in-game.
