Ok, so the tree will follow the camera rotation to always face it.Īnother issue is that if your tree faces your camera but not the lamp, you will get a tiny shadow or a weak shadow. Fill the target object name with the camera name. Go to Object panel (F4) and add a "Copy rotation" constraint. (Uvmapping is another topic not explained here)ĭownlad the. I have UVmapped the plane to see our tree in the 3D view so you can understand what happened easily. In texture map input, tick Cube because our plane is vertical now. This was to fix correct rotation and size before constraint. Select your tree object, press N and fill RotZ: to 0. Third, you must be able to duplicate your 2D objects (in our case, trees) to spread them among your scene. Second, their shadows must fit with your main shadow lamp. We must be careful using 2D objects.įirst, 2D images always have to face the camera. This a good start, but a single tree is one thing, a forest is another. Tip: If you don't see the tree transparent shadow on the ground, tick the TraShadow button of the ground material (not the tree material). Move the plane until the base just reaches the ground. We can resize it by the pressing the "S" button and moving until we get 8 units tall.
That's a bit small for that kind of tree. This also means that our tree is 6.64 units tall. In our example, the texture size is 477圆64px so : select the plane object, press "N" and set the dimensions as follow. For example if your texture is 500x1000px, your plane could be 2.5x5 blender units. Plane dimensions should be the same ratio as the texture size. Tick Ztransp, Shadeless, put Alpha slider to 0. Tick "UseAlpha" and the "Alpha" button near the preview to see transparency. Create a new texture for this material, choose "bitmap" as type and load your tree picture. (A green grass plane with a sunlight and a blue sky :)įirst, create a vertical plane object in the center of your grass plot.Ĭreate a new material for this plane object in the shading panel (F5). To make it easier, this a Blender start scene where your tree could grow in serenity. Tree cut out picture in PNG Create your tree in Blender Once it's done save your picture in a format that supports an alpha layer, PNG is a good choice. The best technique is to use layer masks and have a blurred transition around the cut out image.
Blender trees on plane software#
When photographing people, make sure feet are horizontal on pictures.Ĭut out the subject in your favorite image software (Gimp, Photoshop). Setting your lens to it's maximum zoom will help avoid the distortion caused by wider angles. Otherwise, take a digital camera and take shots of what's around you. You could skip this part by finding libraries of these cut out pictures of trees and people on the web.
