After I changed the transparency of the terrain, I added Cesium Polygon Raster Overlay, Add this component to achieve the clipping effect. However, after adding this component, it does not display properly. So I would like to ask that the clipping components do not support translucent materials.
If supported, how to make, clipping components can also be displayed normally under translucent materials.
The first image is a clipping normal display.(Material not modified)
How are you doing the translucency? I just tried setting the Material property on a tileset with clipping to the MI_CesiumThreeOverlaysAndClippingTranslucent material instance, and the clipping seems to still work just fine.
If youâre using a custom material, youâll need to make sure that material includes clipping support. Take a look at how itâs done in the material above.
Thank you for your answer. I donât actually know how to use this MI_CesiumThreeOverlaysAndClippingTranslucent material instance. I just changed M_CesiumBaseMaterial.
Put this material in, It didnât work.
If you can support both cropping and translucency, Could you tell me your production process in detail.Or tell me how you just used this material instance correctly.
really appreciate.
Unless your tileset is inherently translucent, you need to use the translucent material in the âMaterialâ slot as well. And if youâve changed M_CesiumBaseMaterial, you may need to undo those changes (you generally shouldnât modify any of the assets that come with Cesium for Unreal).
What part donât you understand? You shared a screenshot showing three fields (Material, Translucent Material, and Water Material). Set all three of those fields to MI_CesiumThreeOverlaysAndClippingTranslucent.
No, you need to put it in all three material properties, as I said in my last message.
If you start by copying MI_CesiumThreeOverlaysAndClippingTranslucent, its Blend Mode should already be set to Translucent. Iâm not quite sure what youâre getting at here.
This is done in order to control transparency. So we need to change the opacity from 1 to 0.
May I ask if this operation is wrong
Those are the skirts, that are meant to hide the cracks between tiles. Theyâre properly translucent like the rest of it, but because thereâs some overlapping geometry (the normal surface plus a vertical skirt), they appear a different color. Thereâs currently no solution to that, unfortunately. For Cesium World Terrain itâs possible (but not implemented) to optionally exclude rendering of the skirts. For other tilesets, like Google Photorealistic 3D Tiles, we donât know which triangles are skirts, so thereâs no a good way to exclude them.
