January 30th, 2015
1. Limitations on CheckMate Lite Certification
CheckMate Lite Certification is reserved for well-made, quality 3D models.
1.2.1 Product pricing must conform to the CheckMate pricing matrix.
1.2.2 Product pricing must be equal to or above the average selling price of comparable models. TurboSquid reserves the right to make changes to prices as necessary.
1.3 File Formats
1.3.1 Native file format must pass inspection before other file formats are inspected.
1.3.2 File formats eligible for inspection are:
- 3ds Max (.max) (Renderers Supported: Scanline / V-Ray / Corona / Arnold / IRay / Mental Ray)
- Maya (.ma / .mb) (Renderers Supported: Software / Hardware / Mental Ray / V-Ray / Arnold)
- CINEMA 4D (.c4d) (Renderers Supported: Advanced / Physical / Arnold / V-Ray)
- Lightwave (.lws) (Renderers Supported: Default)
- Blender (.blend) (Renderers Supported: Standard / Cycles)
22.214.171.124 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.
126.96.36.199 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.
1.4 Scenes, Sets & Collections
1.4.1 Scenes are eligible for certification.
1.4.2 Collections are not eligible for certification unless all of the models within that collection have already been certified individually as CheckMate Pro or CheckMate Lite.
- Collections that contain all CheckMate Pro models can be submitted for Pro certification.
- Collections that contain all CheckMate Lite models can be submitted for Lite certification.
- Collections that contain both CheckMate Lite and Pro models can be submitted for Lite certification.
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.
1.7 Payment Information
In order to have 3D models CheckMate Certified, the publishing member must fill out accurate and up-to-date Payment Information for the TurboSquid account.
- Standards for 3D Model Inspection
2.1.2 Textures are 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.
2.2.1 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 explicitly state this.
2.2.4 The native model file must be in the same position and framing as the Signature and Context Signature images. Additional non-native file formats that are published simply need to open so the full model is visible in the viewport with no hidden parts but do not have to match pose and framing of the native file.
- Standards for Product Presentation
188.8.131.52 Signature image should show only the model and no additional elements. You can include a shadow under or behind the model (not required). Any included shadows are allowed to clip the edge of the bottom and lower third of the image only.
184.108.40.206 Signature image should show the entire model inside the image boundaries. Exceptions can be made for closeups of characters and other vertically oriented models like skyscrapers, street lights, etc.
220.127.116.11 Signature image must be rendered against background color RGB (247,247,247) in .PNG format. Be sure to check your final image before posting, often JPG compression changes the RGB value to something other than 247.
18.104.22.168 Minimum resolution of 1480 x 800 (1 to 1.85 aspect ratio) is highly recommended. Image aspect ratios from 1 to 1.5 (minimum 1480 x 988 pixels) through 1 to 1.9 (minimum 1480 x 779 pixels) are acceptable for presentation imagery.
22.214.171.124 Other spec requirements for Signature Image also apply (no text, logos or borders.). Watermarks can be used only as described and subject to inspector discretion. Turntables are not allowed as the Signature or Context Signature Image.
126.96.36.199 Minimum resolution of 1480 x 800 (1 to 1.85 aspect ratio) is highly recommended. Image aspect ratios from 1 to 1.5 (minimum 1480 x 988 pixels) through 1 to 1.9 (minimum 1480 x 779 pixels) are acceptable for presentation imagery.
188.8.131.52 This set of rendered imagery shows off the model’s quality, detail and aesthetic appeal from a variety of angles and positions. This is where you get to show off your skill to potential customers, so spend time on these.
184.108.40.206 Minimum resolution of 1480 x 800 (1 to 1.85 aspect ratio) is highly recommended. Image aspect ratios from 1 to 1.5 (minimum 1480 x 988 pixels) through 1 to 1.9 (minimum 1480 x 779 pixels) are acceptable for presentation imagery.
It is usually necessary to include at least 3-4 closeups of various parts of the geometry to fully show the topology. On a complex model, more wireframes might be required to give a potential customer the visual information they need to make a buying decision.
220.127.116.11 There must be a sufficient contrast between the background/object and wire colors to clearly display the wireframe applied to the model. It is highly recommended that the background/object uses a neutral tone, but is not required. The background and object do not have to share the same tone or color.
18.104.22.168 Minimum resolution of 1480 x 800 (1 to 1.85 aspect ratio) is highly recommended. Image aspect ratios from 1 to 1.5 (minimum 1480 x 988 pixels) through 1 to 1.9 (minimum 1480 x 779 pixels) are acceptable for presentation imagery.
22.214.171.124 Turntable is a minimum of 18 frames long, starting at the front of the model and turning in a counter-clockwise direction. Animation should have an equal number of degrees between frames and should loop seamlessly without slowing down.
126.96.36.199 Exception for architecture – interiors can have a centrally located camera that rotates looking outward, scenes and exteriors can substitute flyovers and flybys for looping animations where appropriate.
3.1.6 Optional Images: Beyond the required imagery explained above (Signature, Context Signature, Product Shots, Wireframes and Turntables), you are encouraged to use your creativity to showcase your talent with additional product shots, turntables, and more. These images must adhere to image size minimums listed in the required imagery above, but may have artist annotations, logos and/or watermarks on them as well.
3.2.1 Includes at least one certifiable file format (See 1.3 File Formats).
3.2.4 All required files archived with the product file in one of the following three ways:
- All bitmap textures are archived with each certifiable model file in a flat file structure.
- All bitmap textures are archived with each certifiable model file in a single subfolder beneath the main product file.
- All bitmap textures required are placed into a single, named ZIP file and uploaded once as a Textures Supporting Items product in the TurboSquid publisher. Certifiable model files are each placed into their own named ZIP files and uploaded on their own. See Bitmap Texture Pathing.
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.
- Polygonal Quads/Tris
- Polygonal Quads only
- Polygonal Tris only
- Polygonal Ngons
3.4.4 All words in the Product Name except articles, conjunctions and prepositions must have initial capital letter. Words that represent acronyms can be all caps, but product Name should not be all caps.
3.5.1 Description is filled in. All descriptions should use proper grammar, punctuation, spelling, capitalization, and correct product names. 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.
