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.
