In this section we shall discuss all that relates to the Render tab in 3DCoat.

Firstly, remember to do NOT hit ESC to cancel a render if you still wish to use the image. You MUST wait until it is complete if you wish to have a final, useable image. Canceling the render will not do this. The render engine must be allowed to continue it’s work until it is complete!.

Render Engine: Select which Render Engine to use for rendering. Currently only Internal render and Renderman (this last must be installed first) are ready to use. More will be added in future developments.
Render: This button starts rendering one frame.
Render Animation: This button initiates the render of frame sequence between several saved scenes. Windows popup show all necessary steps to do this render type.
View size: This allows to choose between rendering the whole screen or a custom size. If you choose custom size you can then key in a value for the size on both X and Y of the area you wish to render.
Render size: This allows you to select a size of output image, and it is only active if you are using a custom size from the view size drop down list. Output image size is proportional to the viewport size.
Realtime Render: Realtime rendering in the viewport. Full Rendering is possible and very practical within 3DCoat, due to its very fast internal renderer. This makes it practical to update the rendered view as you move your Camera in relation to your model or scene, letting you see interactively the effect of multiple, colored light sources, soft shadows and depth of field. You can also combine all of these with an overlay of your Retopo Mesh, for effect or reference purposes.


Use Panorama as Environment: Use panorama as environment light source. Otherwise white evenly distributed lights will be used as environment.
Exposure: Overall brightness of the rendered image.
Environment Light: With this parameter you can change your lightening type. Zero value will give you direct lightening, 100 – Hemitype lightening.
DOF degree. Depth of field focus. This option will produce lens focus effect on your image. With this parameter set the distance from the DOF plane where objects remain in focus.
DOF plane position: This slider moves a red plane forward or backward from the screen to set the center of the depth of focus. Use the slider above to set the distance from the plane (in front and back) where objects remain in focus.

Extra Light

Add Light: Add additional light sources to your scene - all controllable as outlined bellow.
Rotation Angle: Angle of rotation of the light around the object in 3D view.
Light Height: Height of the light relative to the horizon.
Light scattering: With this parameter you can adjust the amount of light that will be scattered. Higher values will give you softer shadows and softer Glossiness on shiny objects.
Camera Target: Lights the object from the camera’s position, making the shadowed areas more visible.
Find Sun: Point the brightest spot on the panorama.
Color: Set the color of your light source.
Intensity: Set the brightness of your light source.
Delete: Delete current Light.


Show DOF plane: Check if you want to show a focus plane where details will look most sharply during DOF rendering.
Store alpha channel: With this option checked alpha channel will be rendered too. You should choose TGA as output to use this option correctly. If you are rendering sequence, TGA will be chosen automatically.
Anti-aliasing: Makes your rendered image look smoothed. Keep it checked.


Denoise: This denoiser is a post-rendering process which analyzes noise in 3D space and reduces it without producing spots while maintaining sharp edges and texture details.
Denoise Level: This blends between the denoised and non-denoised image. The default value of 30 provides good balance between denoising and fine detail.
Show Denoised Image: Display denoised render result on the viewport.


No Shadows: Render the scene without shadows.
ShadowmapSize: The size of the shadow map image that 3DCoat renders when creating shadows. A larger shadow map image produces more detailed shadows at a higher cost to rendering performance; a smaller shadow map renders more quickly but results in pixelation at the edges of shadows.
Controls how quickly the shadows are computed:
Fast: Compute fast.
Optimal: (default).
Quality: Compute slowly the shadows.


Hide Visual Guides: Hide symmetry plane, 3D-grid and axis.
Show Retopo Mesh: Show retopo mesh in Render room.

Render Output

Render frame sequence: Check this option for rendering out “Turntable” and “Fly-by” animations. Fly-by positions are determined based on your selections under the “Camera” drop-down menu: “Add camera shortcut . . . “ for each Camera position in the Fly-by. If you check it an additional parameters will appear:
Render result: (if Render frame sequence is unchecked). Choose image format and a folder to store your rendered scene.
Folder to store images: (if Render frame sequence is checked). Name of folder that will be created to store rendered frames. The folder is placed to Install dir/RenderedImages/…
Show Image Sequence Folder: Show where to store rendered images. Note that you can’t specify the folder on you hard drive where to store rendered images.
Save lossless images: Save images in lossless format (TGA or BMP).
Don’t overwrite files: Files will not be overwritten during sequence rendering if checked.
Closed spline: Use this option if you have several camera shortcuts set up in the scene. In this case ‘camera flight’ trajectory will be closed.
Move Around Shortcuts: Move camera around interpolated trajectory that goes through camera shortcuts.


Rays per frame: Set up maximal number of traced rays that are rendered per frame of animation. Rendering time is directly proportional to this value. Higher numbers take longer to render.
Frames to render: Sets the total number of frames that will be rendered to complete a circuit of Camera rendering positions.
Counter clockwise: Reverse the direction of the default Camera rendering positions.
Render sub sequence: Check this option if you want to render or re-render not all frames but only some. If checked you must set the first and the last frame to render.

Essential renderer update!
Screen Space Reflections and Lights! The renderer provides much more realistic results now. Enable Beta Tools to get access to the feature, and then tick corresponding checkboxes in the Render room.
