For example, if the level was set to 0.5 then effectively in AR it will be 2 x times stronger than it would appear on the configurator. **How to Solve This** * To reduce the bump strength simply edit the bump map using image editor controllers to reduce the height. Then set the bump level at 1 value. #### Other Parameters Not Supported * Emissive * Metallic texture (Use metalness from the Blue channel instead) * Roughness texture (Use roughness from the Green channel instead) * Depth pre-pass and separate culling pass * Ambient texture strength * Real-time filtering * Subsurface * Anisotropy * Clear Coat * Sheen If you need any help or have any questions feel free to reach out to Mimeeq support. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.mimeeq.com/augmented-reality/unsupported-parameters.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
