Paint fx trees6/12/2023 The density of the brush strokes needs to be kept low. To tweak parameters for your brush stroke in the Attribute Editor: Lets control the creation of your vegetation by tweaking parameters inside the Attribute Editor. Select the brush stroke and press the Control + A keys. In the Attribute Editor, check Sample Density and Tube Segments, which are the main parameters. Two or three types of trees are needed for your scene in Maya. Once you import the trees in Virtools, you will clone them to create a whole forest. The limit for the total number of polygons created inside a scene is 50,000. To view the polygonal count, go to the top menu, and select Display > Head Up Display > Poly Count. Conversion of 3D Models to Polygonal Meshes Check the number of Faces rendered in the scene. To convert the 3D Paint Effect to polygonal meshes: Lets convert the Paint Effects to 3D objects made of polygonal meshes. Select one of the strokes from the Outliner window or from the perspective view. Choose Modify > Convert > Paint Effects To Polygons. The output from the conversion is a high-resolution model with a high polygonal count. Lets see how Maya can help you reduce the polygonal count. To reduce the number of polygons for a tree: Select the Modeling module in the box located on the left of the Status Line. Lets control the number of polygons for the tree. Go to Display > Heads on Display > Polygon Count. Go to the Rendering menu and select Paint Effect > Paint Effects Mesh Quality.ĭecrease the number of polygons by moving the sliders to the left for Tube Sections and Segment, and check the number of polygons on the Polygon Count. You will notice that this operation can radically alter the shape of the model. In most cases, you will need to use the following polygon reduction to reduce the number of polygons while keeping the integrity of the 3D object. Select a tree and choose Polygons > Reduce. Click on the box located on the right of the word to open the Polygon Reduce Options dialog window.Įnter the percentage of reduction. Check the following parameters, and keep Mesh Borders, UV borders, Hard Edges. Keep reducing the polygon count until your tree has less than 15,000 polygons. If you get a message saying Cannot Reduce Polygonal Object with Nonmanifold Geometry, go to the top menu and select Polygons > Cleanup. Click on the box located on the right of the word to open the Polygon Cleanup Options dialog window. Paint Effects strokes render seamlessly with the rest of your scene during a post process in the final render.Go to Other and check Nonmanifold Geometry and Normals and Geometry. You can get immediate high-quality feedback by rendering brush strokes while you paint. Create your own brushes by setting shading, illumination, shadow, glow, tube, gap, and flow animation attributes or by modifying the attributes for the preset brushes. For example, you can make plants grow, make long hair blow in the wind, or make a river flow.Ĭhoose from one of the many preset brushes and paint realistic effects like plants, hair, fire, feathers, oil paints, pastels, and watercolors, or blend the preset brushes to create custom effects. You can also apply dynamic forces to the effects you paint in your scenes and animate the display and movement of the effects. Imagine being able to paint an orchard in your scene where the painted trees exist as objects that your characters can move around. Scene, that same brush stroke produces these entities three-dimensionally. On a 2D canvas, one brush stroke can produce complex images, for example trees or flowers. Paint Effects goes beyond traditional painting-you can paint entire particle effects with a single brush stroke.
