MDK2 on the Dreamcast did render-to-texture to do mirrors. https://youtu.be/-nVw_q3yEA4?t=210 https://youtu.be/-nVw_q3yEA4?t=210 The PC version lacked all R2T effects. The developers went with "Chaotic Insane", and replaced the mirrors with a colored noise texture, adding a sign saying, "Your reflection is not available at this time --Management". https://youtu.be/xuONTSKjfNE?t=259 https://youtu.be/xuONTSKjfNE?t=259 On a related note, R2T was also used in a cutscene. A video broadcast used R2T on the Dreamcast, and on other versions they just flattened the character placed it inside the monitor, and tweaked the camera work to try to hide it.

I never understood why render to texture looks so bad in mirrors if it works so good in Portal (not a reflection but it seems like the same problem?) Isn't it just a matter of properly calculating the camera position/frustum so that it is perspective-correct? Portal has the same issue[0] until you properly position the camera. What makes reflections different? [0] https://m.youtube.com/watch?v=NGeZCAi2bJs https://m.youtube.com/watch?v=NGeZCAi2bJs 2:50, 4:05, 5:06, 6:58

  Portal does not render to texture, it just renders different content, making use of depth/stencil buffers for masking. This can work for plain mirrors, but the advantage of RTT is that you can sample the texture at arbitrary points, so it can be distorted.

    I didn't mean Portal specific implementation but rather the mechanic. Check the video I linked to. Isn't that RTT?

      It probably is, but that is a hobbyist implementation. How good RTT looks depends a lot on the resolution, rendering the scene a second time to another high resolution target is not necessarily feasible or justified.
