220.127.116.11 Product must include at least one of the above file formats as its native file format in order to be considered for CheckMate Lite certification.
18.104.22.168 Other file formats are not inspected for CheckMate Lite certification.
1.3.3 Certification by product - CheckMate Lite certification is awarded on a per-product basis. In order for the product to be certified as CheckMate Lite, all certifiable formats listed in 1.3.2 must pass the CheckMate Lite standard.
1.5 Standard or Editorial License Only - Models with Custom Licenses are not eligible for certification.
1.6 SquidGuild Only - CheckMate Lite Certification is available only for 3D models published by SquidGuild members.

2. Standards for 3D Model Inspection
2.1 Textures and Materials
2.1.1 No errors on opening - Model file must open without texture-related errors (missing textures, corrupt textures, etc.)
2.1.2 Texture correct in renderings - When model is rendered, texture placement must match thumbnails with reasonable accuracy. This is a subjective standard designed to ensure the model's UV mapping is as advertised, and that the customer will get what he/she expects.
2.1.3 At least one material must be applied to each object to represent real-world object surfaces. The customer should be able to render the model upon purchase and get quality surface representation.
2.1.4 No texture paths referenced by model. Any texture paths must be stripped from model file. See Texture References.
2.2 Model is error-free
2.2.1 No errors on opening - When model is loaded in native application, no errors about missing files, plug-ins, or textures. If a third-party renderer or plug-in is required and not listed in the product information fields, then the Description must say so.
2.2.2 No corrupt files - Model, textures, and any other files included in the product must open cleanly.
2.2.3 The model is a reasonable representation of what is shown in thumbnails.
2.2.4 Model must be in the same position and framing as the signature and secondary image
3. Standards for Product Preview
3.1 Preview Images
3.1.1 Rendered Preview Images Requirements - At least five (5) rendered images with these attributes:
22.214.171.124 600 x 600 resolution minimum. (Only four (4) rendered images will be visible on the product page after certification, the one signature image will only display in the search results).
126.96.36.199 Set of rendered thumbnails show the model from a variety of angles
188.8.131.52 Turntables are not required for CheckMate Lite, but if turntables are submitted they should conform to the turntables standards for CheckMate Pro, with the exception that the turntables can be 600 x 600 (the Pro resolution is not required).
3.1.2 Signature Image Requirements - Image for Search results, set up in Publisher
184.108.40.206 600 x 600 resolution minimum
220.127.116.11 Square resolution - If image resolution is above 600x600, the resolution must be 1200x1200, 1600x1600, or other square resolution.
18.104.22.168 No text, borders, or overlay imagery. No watermarking permitted.
22.214.171.124 Shows only the model and no additional elements. Can include a shadow under or behind the model. Shadows are allowed to clip the edge of the bottom and lower third of the image only.
126.96.36.199 Shows the entire model. Exceptions can be made for closeups of characters and other models, at inspector discretion.
188.8.131.52 Rendered against background color RGB (247,247,247). Be sure to check your image, often JPG compression changes the RGB value to something other than 247.
184.108.40.206 Entire rendered model inside image boundaries
220.127.116.11 Exceptions for interior/exterior architectural scenes, terrains and closeups:
18.104.22.168.1 Model does not have to fit inside image, but can bleed off the edges. 22.214.171.124.2 Background can be a sky or other simple, appropriate background. 126.96.36.199.3 If sky or other background elements shown in Signature Image are not included with the product, this must be explicitly stated in Description.
3.1.3 Second Rendered Preview Image Requirements - The second thumbnail in Publisher (just after Signature Image) must be a rendered thumbnail that meets these requirements:
188.8.131.52 Image shows the model with exactly the same pose and angle as Signature Image. Other spec requirements for signature image also apply (square, no text, logos or borders). Turntables are not allowed as the signature or second image. Watermarking permitted on second image.
184.108.40.206 Image includes background/environment that is dark, realistic or best highlights the quality of the model (inspector discretion).
3.1.4 Wireframe Image Requirements - At least two (2) wireframe images with these attributes:
220.127.116.11 600 x 600 resolution minimum
18.104.22.168 Square resolution - If image resolution is above 600x600, the resolution must be 1200x1200, 1600x1600, or other square resolution.
22.214.171.124 Set of wireframes that show only the model from different angles and/or closeups. The full set of wireframes must show all the model's topology clearly via closeups and various angles.
126.96.36.199 Shows wireframe from visible side of model only (not see-through)
188.8.131.52 Subdivision wireframes must show actual render iterations without the use of Isoline Display
3.2 Main Product Files
3.2.1 Includes at least one certifiable file format (See 1.3 File Formats)
3.2.3 Software version is specified for all certifiable files
3.2.4 All required files archived with product file
184.108.40.206 Textures must be archived with each certifiable model file.
220.127.116.11 Each archive must be a flat file structure with no folders or subfolders. See Texture References.
3.2.5 Archives should not contain multiple renderer versions; separate downloads should be provided for different renderers.
3.3 3D Model Specifications
3.3.1 Polygon Count value matches poly count in native file format - If you've applied subdivision to the native file format which is removable (as with a TurboSmooth modifier in 3ds Max or an editable history in Maya) you must enter the polygon count without subdivision.
3.3.2 Vertex Count value matches vertex count in native file format before subdivision,
3.3.3 In the Geometry field, the only acceptable options for CheckMate Lite are:
Polygonal Quads only
Polygonal Tris only
3.3.4 All product specification fields are accurate with respect to model being submitted to certification.

Descriptions can include information about the model (examples: are cameras and lights included, number of objects in scene, subdivision information). Optional information can include information about the object the model represents.
3.5.2 Third-party plug-ins or renderers used or referenced in model specified - If the renderer in the model file is set to a non-default renderer, or if materials are those from a non-default renderer, state this in Description.
