# Advanced Techniques ## Some tips for render baking * mirror reflections work best if you set Fresnel to 0.0 and the Reflectivity higher then you would in a regular render * for better outer reflections add an image texture containing an environment map containing a simple sky and ground and set its mapping to **Reflection**, its influence to **Color** and the Blend to **Screen**. * render baking is way slower then regular rendering, so try to avoid the expensive mirror reflections with a gloss amount lower then 1.0 * render baking does not use anti-aliasing! That's why you need higher sample rates for ambient occlusion, Area-Lights, Ray-traced soft shadows and things like mirror reflections. It's best to post-process the render baked images with a image-based antialising in your Image-Editor to reduce noise in the texture and to be able to reduce sample rates during render baking. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://xp2b-docs.gitbook.io/xplane2blender-docs/index-2/advanced_techniques.md?ask= ``` The question should be specific, self-contained, and written in natural language.
