This means that the baking process will generate separate texture maps for each polygroup, even if they were originally part of a larger mesh with a single UV set.&nbsp;<\/p>\n\n\n\n<p><strong>When to use it:<\/strong><\/p>\n\n\n\n<p>This technique is particularly useful when you want to apply different materials or texture details to different parts of a model, or when you&#8217;re working with models that have complex or overlapping UVs.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Baking Process<\/h3>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<p><strong>Import your model:<\/strong> Import your high-poly model into 3DCoat.&nbsp;<\/p>\n\n\n\n<p><strong>Create Polygroups:<\/strong> If your model doesn&#8217;t have them already, create polygroups in the Retopo room, either manually or using auto-retopology tools.&nbsp;<br \/><strong>Prepare for Baking:<\/strong> In the Retopo room, select the retopologized mesh and navigate to the Bake option.&nbsp;<br \/><strong>Enable &#8220;Treat Poly Groups as Paint Objects&#8221;:<\/strong> This option tells 3DCoat to treat each polygroup as a separate UV set for baking.&nbsp;<br \/><strong>Choose your settings:<\/strong> Select the desired baking settings, such as the type of normal map (per-pixel or microvertex) and other texture maps you want to bake.&nbsp;<br \/><strong>Bake:<\/strong> Initiate the baking process.&nbsp;<br \/><strong>Result:<\/strong> 3DCoat will generate separate texture maps for each polygroup, allowing you to apply different materials or texture details to each part of your model.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Benefits of Baking by Polygroup<\/h3>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Increased Flexibility:<\/strong> You can apply different materials and textures to different parts of your model.<\/li>\n\n\n\n<li><strong>Improved Texture Efficiency:<\/strong> By separating the model into polygroups, you can optimize texture usage and reduce texture stretching.<\/li>\n\n\n\n<li><strong>Easier Texture Editing:<\/strong> Each polygroup can be edited as a separate texture, making it easier to refine and adjust details.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>In essence, baking by polygroup in 3DCoat provides a powerful way to manage and apply textures to complex models, allowing for greater artistic control and more efficient texture usage.<\/p>\n","protected":false},"author":3,"featured_media":0,"parent":8265,"menu_order":0,"template":"","manualdocumentationcategory":[9],"manual_doc_tag":[],"class_list":["post-12601","manual_documentation","type-manual_documentation","status-publish","hentry","manualdocumentationcategory-manual"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.3 -
