![]() You can override this default setting with Material-specific and input-specific bake settings. When Bake Material Inputs is enabled, this setting specifies the default size of the baked texture that contains the Material input. For simple texture or constant expressions, it uses Material expression matching. The exporter only uses baking for complex material inputs. For materials that don't use mesh-specific data, the exporter uses a simple plane. Use Mesh Data: If a Material input uses mesh-specific data such as vertex color, world position, vector transform nodes and so on, this setting includes that data in the Material baking process, and the resulting texture. Simple: If a material input needs baking, then only use a simple plane as mesh data. Specifies whether to bake a Material into a texture, and if so, how to bake it.ĭisabled: Never use material baking and only rely on material expression matching. If the exporter does not find a more specific setting for a given input on a given Material Asset, it uses the global default. The global default settings are the ultimate fallback settings.

For any given input on a given Material Asset, the exporter prioritizes settings in the following order. The glTF exporter uses the most specific setting it can find. How the glTF Exporter Applies Material Bake Settings ![]() We recommend that you avoid view-dependent expressions when you export Materials. ![]() Dynamic nodes such as Time, Camera Position, and Reflection Vector become static. ![]() When the glTF exporter bakes a material, it evaluates each input expression, pixel by pixel, at that moment. Material baking works best, and most accurately for Materials that do not depend on when or how they are viewed (for example, things such as time or viewing angle). This can happen frequently because most Unreal Engine Material inputs use more advanced expressions than expression matching supports. If expression matching fails, it falls back to material baking. When you export a Material, the exporter tries expression matching first. Material baking: supports most Material expression patterns, but is slower, and requires configuration. Material expression matching: faster and more accurate, but supports only simple Material expression patterns. To convert an Unreal Engine Material to glTF, the exporter uses the following methods, in the following order: In the glTF format, some inputs share the same texture (for example, Metallic / Roughness and Base Color / Opacity (Mask) ). Instead, it allows a single texture or constant for each material input. The glTF workflow is similar to Unreal Engine's workflow, but does not support arbitrary material expressions. The glTF format uses a Metallic / Roughness physically-based rendering (PBR) workflow that can produce photorealistic materials. When you export an Asset that references other content, the exporter can export some of that content as well.Īssets that you can export directly include the following:Ĭontent that you can export indirectly, when a supported Asset references it, includes the following: The glTF exporter can export several types of Asset from Unreal Engine. This page explains what kind of content you can export using glTF, and describes how the glTF exporter handles each type of content. GlTF is a data-driven format, and does not support everything in Unreal Engine. Variants Supported by the EPIC_level_variant_sets Extension
