The Planar Retopo<\/em> is a one-click retopo tool, it uses your object\u2019s UV to position a plane around your object. It works best with flat or tube-shaped objects. But you can use it on almost every shape as long as it has a proper UV.<\/p>\n

How it works:<\/strong><\/span><\/p>[\/et_pb_text][et_pb_text _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”]

When using Planar Retopo the most critical part is the UV of the original mesh.<\/p>\n

You should try to unwrap it in a way that covers almost all the UV Area<\/strong>, similar to a poly plane.<\/p>[\/et_pb_text][et_pb_image src=”http:\/\/cgelementary.com\/wp-content\/uploads\/planarRetopo.jpg” title_text=”planarRetopo” _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”]

As you can see in the above image, it is very important to properly unwrap your mesh and make sure to merge all the UV shells into a single UV island. This will help you avoid seams and stretching in your topology.<\/p>\n

But even in the above image if we look at the behind of the object we can find overlapping seems.<\/p>[\/et_pb_text][et_pb_image src=”http:\/\/cgelementary.com\/wp-content\/uploads\/planarRetopoUV.jpg” title_text=”planarRetopoUV” _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”]

So it is also best that you flatten the borders of your UVs, this will help with the seam line that exists on the edge of the plane.<\/p>\n

In most cases, you don\u2019t need to use any special tool or technique you can just select UVs on every side and use the scale tool to flatten them.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.20.2″ _module_preset=”default” width=”100%” custom_padding=”0px|||||” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”]

After that, you can pin the border UVs and use \u201csmooth\u201d and \u201coptimize\u201d tools to relax the rest of the UVs and have a cleaner seam.<\/p>\n

although you can just ignore this part, merge vertices, and use the sculpting tool to relax the seam.<\/p>[\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”http:\/\/cgelementary.com\/wp-content\/uploads\/planarRetopoUVSmoothSculpt.jpg” title_text=”planarRetopoUVSmoothSculpt” _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.20.2″ _module_preset=”default” width=”100%” custom_padding=”0px|||||” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”]

Inside the channel box, you can use the Subdivision attributes of the polyPlane to control the division of your new mesh.<\/p>\n

\u00a0The Width and Height attributes don\u2019t do anything here.<\/p>[\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”http:\/\/cgelementary.com\/wp-content\/uploads\/planarRetopo_Subdiv.jpg” title_text=”planarRetopo_Subdiv” _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_section]<\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","template":"","knowledgebase_cat":[129],"class_list":["post-4294","knowledgebase","type-knowledgebase","status-publish","hentry","knowledgebase_cat-modeling_tools"],"_links":{"self":[{"href":"https:\/\/cgelementary.com\/index.php?rest_route=\/wp\/v2\/knowledgebase\/4294","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cgelementary.com\/index.php?rest_route=\/wp\/v2\/knowledgebase"}],"about":[{"href":"https:\/\/cgelementary.com\/index.php?rest_route=\/wp\/v2\/types\/knowledgebase"}],"author":[{"embeddable":true,"href":"https:\/\/cgelementary.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/cgelementary.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=4294"}],"version-history":[{"count":6,"href":"https:\/\/cgelementary.com\/index.php?rest_route=\/wp\/v2\/knowledgebase\/4294\/revisions"}],"predecessor-version":[{"id":5427,"href":"https:\/\/cgelementary.com\/index.php?rest_route=\/wp\/v2\/knowledgebase\/4294\/revisions\/5427"}],"wp:attachment":[{"href":"https:\/\/cgelementary.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=4294"}],"wp:term":[{"taxonomy":"knowledgebase_cat","embeddable":true,"href":"https:\/\/cgelementary.com\/index.php?rest_route=%2Fwp%2Fv2%2Fknowledgebase_cat&post=4294"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
