Hello, I'd like to ask about the render support three.js Is the bump in the map

[xiaxc1]

If I can continue to add bump texture, how can I implement it?

[elfrank]

xiaxc1 the renderer supports normal maps already. Is there a particular reason why you would prefer bump maps over normal maps?

Hello, thank you for your reply. Because the two images are different, the bump map needs a grayscale image, while the normal map image is relatively high, the bump effect achieved by the bump map is a little stronger
